IPICS

Cisco has introduced an IP Interoperability and Collaboration Systems (IPICS) platform that enables public agencies using different voice radio networks to communicate. The platform should facilitate communication between fire departments, police, military, etc. Different networks are virtualized using IP as a base. Cisco IPICS Voice over IP XML Services drives the IPICS system that consists of hardware, software, and the IPICS Push-to-Talk Management Center (PMC).

The push-to-talk radio has eight channels and it supports UHF, VHF frequencies, cell phone networks, PSTN, VoIP, etc. The product is set to be released in 2006. Cisco has pegged the market for radio systems at $ 6 billion - $ 8 billion annually. IPICS provides an infrastructure that will allow organizations to scale their communications network in a cost-effective manner. IPICS also has an event policy-based IM messaging component that can be employed for converting text messages to speech that can be relayed over interoperable networks.

NetStructure Host Media Processing

Intel is designing products that will help companies to implement VoIP and at the same time obtain the maximum benefit from their investments in legacy systems. Intel has released the NetStructure Host Media Processing (HMP) 1.5 software for Linux; it supports up to 120 video channels that can be utilized for services such as video mail, video color ring back, video caller ID, etc.

Media enterprises can avail VoIP telephony by using the host media processing technology provided by Intel. In the next three months, Intel will release the NetStructure HMP 2.0 for Windows and the NetStructure Digital Network Interface Boards. Intel has implemented a hybrid VoIP solution at its site at Parsippany, New Jersey. The solution will help bring down MAC costs by 72% and reduce the floor-space requirements for equipment by 89%.

Intel has released a reference design, the Converged Application Platform for the Distributed Enterprise, which aims to facilitate the deployment of multimedia services by SMBs. The design allows integration of discrete pieces within the network into a single device. The working prototype uses HMP and processors and should enable telecom vendors to access the market faster.

Petition against FCC ruling

A number of civil liberties groups and technology companies have filed a petition in the court stating that in adopting the rules related to phone-tapping of Internet calls by the law-enforcement agencies, the FCC has exceeded its statutory authority. The plaintiffs for the petition filed with the U.S. Court of Appeals for the District of Columbia Circuit include companies such as Sun Microsystems, Pulver.com and groups like the American Library Association.

According to the petitioners, the legal wiretapping rules prepared by FCC cover technologies that are not covered by the Congress and its mandates are going to be difficult to meet. The petition states that the order exceeds the authority of the commission, is arbitrary, not supported by evidence, is contrary to the law, and a threat to the privacy of Internet users. The petitioners argue that the government has not provided any evidence that interception of Internet calls is difficult and by extending a law that is meant exclusively for PSTN, it is hurting innovation.

Moreover, ISPs will have to restructure their networks for the benefit of police authorities in order to comply with the requirements by early 2007. Networks will have to be built with “backdoors” that enable law enforcement to eavesdrop on private communication. Legal experts are of the opinion that the government is entitled to monitor communication, regardless of the technology used for transmission. However, it needs to have a proper search warrant and reasonable grounds for doing so.

It is proper, according to some experts, that technology should accommodate the requirements of law-enforcement agencies and that the law-enforcement agencies do not take any extra-constitutional steps. ISP’s would prefer that the case is interpreted in a manner that exempts them from complying with CALEA otherwise they will have to buy and install the devices for wiretapping. Those who support the inclusion of IP telephony under the wiretapping laws contend that if such a step is not taken, VoIP could become a communication tool for terrorists.

Security loopholes

Skype Technologies S.A. has released two advisories regarding security vulnerabilities that can result in DoS and system access attacks. Since Skype is a widely used application and operates from behind firewalls, the threat to security is magnified.

The revelation regarding the security problems with Skype can have far-reaching implications for the company with a user-base of 60 million users, of which 30% are paid users. According to Secunia Inc. these security risks are highly critical and users are well advised to download the relevant patches as soon as possible. Skype for Windows Releases 1.1.*.0 through 1.4.*.83 is vulnerable to these threats. Skype for Windows Release 1.4.*.83 and prior, Skype for Mac OS X Release 1.3.*.16 and prior, Skype for Linux Release 1.2.*.17 and prior and Skype for Pocket PC Release 1.1.*.6 and prior are vulnerable to the DoS attacks.

A boundary error that occurs when Skype-specific URI types like "callto://" and "skype://" are handled can lead to a buffer overflow resulting in arbitrary code execution. This may even crash the Skype client.

Dept. of Justice regulation

According to the department of justice, business users in 19 cities could face higher telecom rates as a result of the mergers between Verizon Communications Inc. and MCI and the acquisition of AT&T Corp. by SBC Communications Inc. In order to ensure that the business users get competitive rates, the Department of Justice has directed these telcos to divest some portions of their fiber-optic networks in 19 cities.

MCI and Verizon are competitors in cities such as Boston, New York, and Philadelphia and they provide connectivity to 350 buildings. A merger would imply no competition to spur competitive pricing for the consumers.

More that 350 buildings in 11 cities including Dallas, Detroit, and Los Angeles are managed by SBC and AT&T. According to the requirement of the Department of Justice, Verizon and SBC will have to offer the connections to the buildings to a single buyer as a long-term lease.

E911 deadline

Lightyear Network Solutions, LLC, Lingo Inc., Nuvio Corp., and i2 Telecom International Inc., have filed a petition with FCC requesting for an extension of the November 28 deadline for compliance regarding 911 services on Internet telephones.

The companies plan to file for a stay order if the response from the FCC is not agreeable to them. Experts are divided in their opinions regarding FCC’s response to the petition. Some feel that given the great deal of significance that the FCC has attached to the ruling, it may not agree on extending the deadline. However, other industry watchers opine that the Internet Telephony industry is moving toward a uniform E911 standard and that the FCC deadline is somewhat unreasonable.

VOIP Inc. is actively implementing the FCC quality requirements in its private network 911, known as VoiceOne. The company, which was set up around 18 months ago, has achieved a $ 50 million run rate. Another example of successfully managing FCC requirements is provided by Intrado Inc., which provides Enhanced 911 services through a number of its E911 deployments in the US.

TDM Centrex Vs IP Centrex

A Centrex Service implies the outsourcing a company’s internal telephony service to a third party. The service includes toll-free calls within the company, extension dialing, IVR/Auto Attendant, Voice Mail, etc. In a Centrex system, the service provider installs the equipment, dedicated to a number of customers, in its central office or at the customer premises.

In a TDM network, several PSTN lines are grouped together to provide toll-free calls within the company and some basic value-added services. The service provider used PSTN Class 5 switches that allowed scalability without any major investments. However, the TDM Centrex model was not very attractive financially for the companies, more so due to the arrival of entry-level PBXs that provided more features. The flexibility offered by PBXs in terms of changing phone numbers and adding subscriber features is appreciated by industry, particularly, the SMBs.

The IP Centrex Model can be implemented in different ways and is not location dependent. The IP-PBX and the phones can be located anywhere on the network. The service can be managed remotely by the provider regardless of whether the IP-PBX is located at the customer site or the provider site.

The fundamental reason behind opting for a Centrex model is to save on the operating costs associated with owning a telephone network. TDM-based Centrex solutions were implemented over the old TDM switches and hence provided the same telephony features as were provided to the Class 5 subscribers. In contrast, the IP Centrex PBX provides features available in enterprise IP-PBXs. The TDM-based PSTN switches did not originally support partitioning which made the execution of simple tasks such as billing and security difficult for the service providers. The IP Centrex solutions are developed to facilitate partitioning and easy management of multiple customers with multi-tenant implementations.

IP-based Centrex models use centrally based application servers that are scalable and hence more suited for providing a host of value added services. As against this, in a TDM network the servers have to be installed locally, the time-to-market was high and CTI support was not easy to implement.

In a TDM Centrex environment, moving a single user from one place to another can cost a company upward of $ 100. Changes cannot be performed by the organization and adds usually mean investing in additional PSTN lines. Moves, adds, and changes (MACs) are easier to accomplish in an IP Centrex model with negligible investment of time and money. Phones can be added by the users themselves by means of a web interface.

Customers of a TDM-based Centrex have to outsource the maintenance to the service provider. A difficult to use DTMF interface is used by customers who wish to alter configurations. In an IP Centrex solution, the management and monitoring activities are shared between the service provider and the end-user by means of an easy to use web-based GUI. Unlike TDM-based Centrex solutions that could only be provided by the Telco, an IP Centrex can be provided by a Telco, an ISP, or an MSO.

VoIP Open Application-Enabling Platforms

Motorola will be releasing VoIP Open Application-Enabling Platforms. These are based on Motorola’s FACT-SIP software that is integrated with the ComStruct(TM) CompactPCI packet voice resource boards. SIP commands are sent across an IP socket by the FACT-SIP software. This enables control of the ComStruct packet voice resource hardware which leads to easy interfacing of the SIP-based applications with the ComStruct hardware so that VoIP enabled applications can be set up easily. tmcnet.com reports:

Motorola also intends to create new VoIP Open Application-Enabling Platform families that integrate FACT-SIP software with MicroTCA(TM) and AdvancedTCA(R) hardware. The increasing adoption of SIP supports Motorola's vision of seamless mobility by making it easier for devices and applications to communicate.

Unified Messaging

SIP is facilitating the marriage of asynchronous applications like email with real-time applications. This enables unified messaging and helps companies stay connected. Interactive Intelligence, 3Com, etc provide unified messaging applications that are capable of working on a message before it enters the email system. The Find Me, Follow Me (FMFM) functionality checks for pre-configured contacts before moving on to the voice mail.

Unified messaging allows companies to prioritize their communication. The cost of these applications is not very high. The application provided by Siemens costs $ 80 per user per year. The cost of SIP phones are falling as well. informationweek.com reports:

Network Computing's poll paints an interesting picture of unified-messaging adoption. Only 17% of 686 respondents use unified messaging. But every one of our respondents from businesses with more than 5,000 employees say their companies have implemented it.

Compatible gadgets

The plethora of wired and wireless communication means such as mobile phones, voice over IP, video, email, IM, etc facilitate communication at any time but not necessarily in a hassle-free manner. Incompatible wireless email and differences in protocols, devices, and standards are the major stumbling blocks.

Research In Motion Ltd. and Palm Inc. have come together to address these problems. The Treo 650 smart phone developed by Palm will the wireless email platform provided by Research In Motion. informationweek.com reports:

Rudolph and Sletten Inc., a construction company, uses BlackBerrys and Treos and has different servers to support them. The company is open to the idea of using a single server for both. "We would definitely be cutting down on costs because we wouldn't need to buy multiple licenses," operations manager James McGibney says.

VoIP security

Since VoIP applications are exposed to the same threats as other IP services, they can also be protected using the same techniques that are used for the other services.

Hijacking of calls can be prevented by setting up sessions for SIP-supported VoIP. A firewall with a Simple Traversal of User Datagram Protocol and network address translators can be used to enable phones to route calls via an external server between the SIP end points. The external server, which can be a registration or a session server, is used for the authentication of the phones.

Along with data security, privacy features high on the list of concerns. This is because unlike PSTN phones, IP phone-tappers do not require a physical connection by means of a wire. Calls that traverse over the Internet can be captured and analyzed with the help of a protocol analyzer.

VoIPSA

The Voice over IP Security Alliance (VoIPSA) has released a classification of the threats that IP telephony is vulnerable to. The VoIP Security Threat Taxonomy is intended to serve as a single reference point for looking up the type and description of threats; thereby facilitating a systematic approach to tackling these threats. The taxonomy has resulted in a clearer understanding of the gravity of the threats; voice spam was considered to be a major threat but according to the taxonomy deceptive practices pose a bigger challenge.

The threats have been classified into four categories that include DoS; unlawful signal or traffic modification; signal interception; and bypass of refused consent. The first two types of threat categories are concerned with the integrity of the network signal. The latter two types of threats are specific to VoIP and concerned particularly with maintaining privacy.

Pricing issues with cable broadband.

Broadband providers are caught on the horns of a dilemma because although customers are going to pay more for broadband they are also expecting more from the service providers. Moreover, once a user is online, he uses the net to avail alternatives to the traditional phone and video services that have been revenue earners for the cable operators and the telecom companies for a long time.

The service providers are trying to figure out ways to make the customers pay more for services such as video file sharing and IP telephony as these can consume greater bandwidth. eweek.com reports:

After all, cable companies don't like to provide Internet access so customers can use BitTorrent, the video file-sharing service. It's not hard to see how it could replace their TV business. And since one of the nation's largest cable companies also makes movies, it's not hard to see that happening.

PSTNs and broadband

VoIP and mobile services have made inroads into the PSTN-based voice services. Coupled with the obsolescence of the PSTN technology, this has resulted in a swift decrease in profits for the PSTN. Many fixed line operators are moving toward a fiber-rich IP-based access network that supports voice, data, and video services.

Alcatel provides an Intelligent Services Access Manager (ISAM), which is an IP/Ethernet platform that supports triple play broadband access. It can be used by PSTNs to implement fully converged next generation networks (NGNs). Reduction in the number of minutes per subscriber, reduced average price per minute, and reduced subscriber base are the three main reasons for the decline in profitability for PSTN. Also, as the networks grow obsolete, the operating costs increase.

TDM-based systems that have been running using narrowband digital loop carriers (DLCs) for around 30 years are nearing the end of their useful life and replacements for parts are difficult to obtain. Broadband and NGN architecture allow operators to work with unmanned locations in cabinets and a minimum number of manned central offices (CO). This network model enables operators to reduce operational costs and scale the network as per requirement with relative ease. Fixed-line operators are investing in voice migration and broadband infrastructure that will enable them to offer high-speed data and video services. alcatel.com reports:

Analog telephone adapters (ATAs) allow connection of traditional phones to broadband access lines. They are a good solution for broadband subscribers willing to sacrifice some of the plain old telephone system (POTS) benefits (such as lifeline or home wiring flexibility) in exchange for low-cost PSTN. However, this is not a cost-effective solution for mass migration of PSTN subscribers into the converged core.

LWAPP

WLANs are moving toward centralized intelligence. The trend is for an architecture that consists of a WAN controller system which is employed for the creation and enforcement of policies across several lightweight access points.

Centralized intelligence for these devices enables efficient management of security, mobility, etc across the WAN. The performance and security of WANs improves and the management becomes easier when functions are divided between the access point and the controller.

The IETF is looking into the development of protocols for managing the communication between the lightweight access points and the WLAN systems.

In traditional WLAN solutions, the access point handles all the traffic handling, security, and mobility, etc. However, this results in the 802.11 traffic being visible only to the individual access point. This can lead to increased management costs as each individual access point must be managed separately. An attack on the network is not visible to everyone on the system and DoS attacks can be neither predicted nor controlled across the WLAN. The security policies for Layers 1, 2, and 3 have a single point of enforcement. Real-time load balancing can not be achieved in an optimal manner. The speed of hand-offs, which is critical for applications such as voice and video, is compromised.

The issue of standardization in a centralized WAN is being looked into in the LWAPP draft, which was prepared by Airespace (acquired by Cisco Systems in March 2005) and NTT DoCoMo. This exercise aims at minimizing the process time in an access point so that the computing resources of the device are used for providing wireless access and not wasted on enforcing policy. The draft also proposes a method for centralized management of policy enforcement for the entire WLAN. An IP routed network or a Layer 2 infrastructure is suggested for providing multivendor access point interoperability.

The LWAPP draft aims to achieve these objectives by means of access point device discovery, information exchange, etc; packet encapsulation, fragmentation, and formatting; management of communication between access points and the wireless system devices. By adopting LWAPP, enterprises can choose interoperable accessible points. This enables them to make decisions keeping in mind the capabilities of the individual access points.

Widespread acceptance of LWAPP should reduce the industry’s dependence on single-vendor proprietary WLAN system devices. Centralized WLAN architectures provided by different vendors can avail secure Layer 2 and 3 networking services by using the open standards solution provided by LWAPP. Vendors can build their applications around a common platform when using LWAPP.

LWAPP was introduced in 2002. It enabled separate management of the real-time traffic, particularly the real-time frame exchange that is accomplished within the access point. Functions such as authentication, security management, etc are performed by the WLAN controllers.

The split MAC functionality of LWAPP was first utilized by the Cisco Centralized WLAN Solution. The solution provided by Cisco enables dynamic RF management across the system and allows dynamic assignment of channels and load balancing. There is only one graphical interface for all the policies such as VLANs and QoS. Uniform security enforcement is facilitated by the enterprise-wide security policies that cover the radio layer, the MAC layer, and the network layer. The Cisco system also facilitates swift hand-offs and quick discovery and remedy of DoS attacks.

Traffic on the WLAN

The performance of WLANs in organizations depends upon the volume and type of traffic that they support. Most organizations install an 802.11b WLAN for data and a separate 802.11a WLAN for voice. The increasing number of entertainment services that include music, games, web-browsing, etc are directed as voice traffic.

The WLAN bandwidth requirements will increase, reducing the number of simultaneous users. There will be greater congestion. QoS, for different types of entertainment traffic, will be more complex to deliver. The number of WLAN access points and their connections to the LAN switch will increase.

Yahoo Messenger and MSN

MSN and Yahoo Messenger are to come together to form the largest IM community numbered at 275 million and growing. The two companies that own the services, i.e. Microsoft Corp. and Yahoo Inc. have stated that the two services will be integrated keeping in mind consumer security and data privacy.

The integrated version is expected to be made available to users in the second quarter of 2006. Users will be able to avail all the IM facilities including PC-to-PC phone calls and add members from both the services on to their lists. The security will be based on SIP for Instant Messaging and Presence Leveraging Extensions (SIMPLE) protocols. SIMPLE, which has been developed by the IETF, enables buddy list subscriptions and notifications and IM commands.

In 2001, AOL had mentioned its desire to employ SIMPLE for its IM service but is using proprietary standards. SIMPLE uses a session mode and a page mode. Session mode is used for setting up a call. Page mode does not employ call setup and is similar to an SMS service for issuing short messages and announcements. eweek.com reports:

Being able to IM with friends and family that use other IM services is the most requested service from users, said Blake Irving, corporate vice president of the MSN Communication Services and Member Platform group at Microsoft. "It's been bubbling up on the request list for years."

FoIP

According to a research report published by Synergy Research Group, the Service VoIP market will be worth $ 2 billion in 2005. The growth of VoIP has firmly placed it as a viable option for mainstream telephony. As companies enter their upgrade cycles, they will migrate to IP telephony.

According to Morgan Stanley, a big share of business outlays is going to be increasingly directed toward VoIP. In the corporate sector, VoIP software and hardware sales will cross $ 11 billion by 2009. An estimate by AMI-Partners puts the spending by SMBs on IP telephony at $ 4.5 billion by 2008. In 2004, SMBs spent around $ 1.2 billion on VoIP, out of which $ 1.1 billion was spent on routers and SIP phones.

A survey conducted by Savatar in which 300 industry decision-makers participated yielded interesting information on the perception patterns in industry regarding VoIP. Reduced monthly bills were cited as a major attraction by 74% of the respondents. Reduced cost of ownership and simplified administration were cited as reasons by 73% and 68% of the respondents, respectively. Bundling of services, such as fax, with VoIP is also a good reason for 40% of the respondents for switching to VoIP.

Major telecom players have initiated moves that will result in reduced subscriber rates. Verizon, for example, is replacing its copper lines with optical fiber networks so that all products finally converge on to a single IP network. Analysts feel the VoIP adoption has gone mainstream. David Lankelevich, eMarketer.com, feels that VoIP will gain mass acceptance in the next two years.

The growth of VoIP is being fostered by factors such as quick resolution of the interoperability issues, increased broadband connectivity, etc. A single IP network for voice and data promises simplified management as there is only a single technology to understand; the reduced number of network elements is easier to manage with fewer IT systems required. A VoIP system helps in performing time-consuming and tedious moving and shifting tasks in a quick manner. In a TDM network, shifting a user while maintaining his extension number entails physical alterations in the network.

In an IP network, a user is not tied down by a physical connection to a specific port. User identification is achieved by the IP address of the phone. This allows users to work with their desk phones by simply plugging them into the LAN from anywhere in the office.

The hurdles to implementing VoIP include ensuring network capability to handle latency-sensitive voice traffic. This can mean expensive upgrades in terms of increasing WAN bandwidth and changing switches and routers. A study conducted by Nemertes Research in November 2004 revealed that the startup costs depended upon factors such as the size of the company and the IP vendor selected to provide the solution.

For a company with 100 users or less, the cost of deploying VoIP can come to $ 763 per person. The costs include IP PBXs and handsets as well as planning and implementation. The cost per user falls down to $ 525 for an organization with 1000 users or more.

Fax is an important service that can be bundled with VoIP. Fax offers advantages in terms of being compatible with several technologies, no changes in format, not editable by the recipient, etc.

The prospect of streamlined and integrated messaging services by deploying VoIP is of interest to a lot of organizations. 58% of the respondents, in a survey conducted by Empirix in February 2005, stated that they intended to run messaging applications on their converged networks.

Fax over IP (FoIP) is easy to deploy for companies that have an IP network in place. IP routers from companies such as Cisco, 3Com, Alcatel, etc are available with a built-in fax component (T.38). bitpipe.com reports:

For smaller organizations exploring VoIP, the big question is “how can we do this without breaking the bank?” As the market heats up there are a range of VoIP solutions with various price points. For such companies also looking to roll-out network fax functionality, a review of the actual cost of a VoIP system as well as a comparison of a boarded fax server versus one that is boardless should be added to the IT checklist.

FCC regulation for tapping VoIP calls

The second principle of the FCC states that consumers have the right to use the service of their choice but subject to the requirements of the law-enforcement agencies. Future services will be assessed by a new order as per CALEA. networkworld.com reports:

If that's not enough, the FCC's arguments about why CALEA should cover VoIP just as easily applies to almost any Internet application. This sounds like the FCC will order that law enforcement approve Internet applications before you can use them.

Mergers create opportunities

The recent mergers involving six big telecom players will result in a new breed of companies promising a host of services including local and long-distance VoIP, broadband Internet connectivity, wireless, etc.

The changing scenario will lead to a need for better vendor management. The present flux can be a good thing for the users who can ask for better rates for the host of bundled services on offer as well as better customer support services.

According to Fred Gratke, Assistant V.P Telecommunications, Burlington Northern and Santa Fe Railway, two or three financially stable national carriers that can offer better service are sufficient to spur competition.

According to J.T Johnson, President, Nemertes Research, a mega carrier offering several services can afford to offer volume discounts and is also less complicated to deal with as compared to interacting with a host of carriers and managing multiple accounts.

Apart from offering volume discounts on bundled services, the carriers can streamline the order processing, billing, and provide prompt troubleshooting. The changes in the internal setup of carriers are already causing billing problems and customer relationship is also being affected.

Paul Lowenwirth, V.P Telecommunications, Viewpointe Archive Services, feels that it is important for customers to ensure that they stay relevant to the carrier’s scheme of things. If customers lose their significance for the large carriers created due to the mega mergers, they risk facing a fall in the standards of service offered to them.

Customers will be required to hone their vendor management skills in order to be able to negotiate the best packages as a result of the new setup emerging in the telecom industry. IT personnel will need to know more than just the technicalities of MPLS and VoIP technologies. Their opinion will be important in drafting service level agreements and redefining the minimum revenue requirements given that data packets are being added to the voice minutes.

The interaction between the provider and client is also set to increase as the complexity of the services provided increases. Thus, a carrier’s ability to help clients utilize their technology along with providing cost savings will matter. Large clients will often pay more in return for improved services such as managed services and carriers playing an active role in securing data.

According to Gartner, half of their clients are signing 3-year contracts and around 20% are opting for 4-5 year contracts to avail greater discounts. A longer contract period is not such a bad idea as prices are not really going down. Moreover, it allows both parties to work out a mutually beneficial service-level agreement.

The spate of mergers is also good news for the smaller players who are stepping in to fill the spaces created due the mergers. These include remote-access companies such as New Edge Networks, virtual network operators such as Virtela Communications, and outsourcers like IBM.

VoIP in business

Several businesses such as the New York-based brokerage firm Coldwell Banker are realizing the benefits offered by Internet telephony. According to Info-Tech Research Group, 50% of all businesses should be using VoIP by 2008 and by 2015 every business will probably be into using IP telephony. techtarget.com reports:

Yet while a host of benefits await-cost savings, efficiencies, applications that can be tied into the system--make no mistake: This is a vendor-driven upgrade. Leading telephony vendors have all but discontinued their traditional time division multiplexing (TDM) private branch exchanges (PBX), opting instead to make all of their products IP-enabled.

Service issues with Vonage

Vonage is a less expensive alternative to POTS and has more features. However, the QoS leaves something to be desired. networkworld.com reports:

The cause of our VoIP tribulations might have something to do with the fact that a few days before moving to Vonage we switched our DSL service from a static IP address to a dynamic one.

Bandwidth.com

Bandwidth.com has launched a new tool that will allow SMBs to test their organization’s readiness for VoIP. The test checks availability of ports, bandwidth, and the extent of latency. These three elements significantly influence the ability of a network to handle both voice and data.

The launch of the new tool coincides with the release of a report by Savatar. According to the report, SMBs that are keen on VoIP implementation do not get adequate information and support from the major VoIP providers.

The major service providers are waking up to the potential SMB market. Microsoft is partnering Qwest and Vonage has teamed up with TowerStream to make their services available to SMBs that are more than 1.5 million in number.

SMBs in every state in the US can avail Bandwidth’s services as the company has extensive collaboration with wholesalers such as AT&T and Level 3. The company is set to spend $ 4.75 million on improving its service to the SMBs.

trueVoice

EarthLink has launched trueVoice, which is a successor to EarthLink Unlimited Voice. Unlike EarthLink Unlimited Voice, which used technology borrowed from Vonage, trueVoice runs on a network that has been built entirely by EarthLink.

trueVoice is available with unlimited local and long-distance calls at $ 24.95 per month and as trueVoice Basic, which is a package of 500 minutes at $ 14.95 per month. Both offers provide 911 service and are free for the first month. EarthLink has around 1.5 million broadband customers, which it is well-positioned to tap for its new offering.

Voicemail and three-way calling are some of the standard features included with trueVoice. Enhanced call forwarding can be purchased for $ 4.95 per month. This feature enables the user to forward a call to up to five numbers. Call-blocking is a new function that allows the users to block up to ten calls.

The trueVoice startup kit includes a free analog terminal adaptor that is required for the compatibility of non-IP phones with the VoIP service. trueVoice customers are provided with an address book that is kept on the Webmail servers. The contact details stored in the address book are automatically integrated with the voice service.

IRCbot

A new variant of the Trojan IRCbot, also known as Fanbot, has been uncovered by MessageLabs. It imitates Skype 1.4. If it is executed, the Trojan displays an error notice. It installs itself in the sysdir%remote.exe and stops shared access and the Windows updates. This is the first time that Skype has been mentioned in a phishing attack.

Competition for Vonage

Even though Vonage has had a head start in the VoIP market, it faces stiff competition from VoIP companies that are more than 1500 in number in the US itself. Moreover, Skype’s acquisition by eBay will probably make the company even more competitive.

Importantly, most of the service providers use the SIP protocol. However, unlike Vonage, they offer interoperability. This flexibility that they offer to their customers could give them an edge over Vonage.

Vonage also charges more for its service. It offers unlimited talk time to three countries, i.e. US, Canada, and Puerto Rico for $ 24.99 each month. The same service is offered by its competitors such as Broadvoice at $ 19.95 every month and it covers twenty two countries. Given the fact that prices are only going to get more and more competitive, Vonage may find it difficult to extricate itself from a business model that it is currently using to service its more than one million customers. If Vonage is acquired by one of the Internet giants, it may be able to survive in a healthy fashion.

VoIP-enabling devices

There are several devices available that VoIP-enable existing phones. Internet Phone Wizard (IPW), developed by Actiontec, is one such device. It provides access to a VoIP line that uses Skype and a POTS line. The IPW does not require a power supply; it is powered by the USB port, which it uses to connect to the PC. The IPW has dimensions 4.5 X 3.25 X 1 inch. Its three ports include two RJ11 ports for an incoming line and the handset and the USB port mentioned earlier.

The IPW can be used to make calls on any of the two lines and one can be put on hold to receive a call on another. At present, the IPW works only with Windows XP and 2000. The device has a flawless design and is a useful addition for Skype users. It is priced at $ 70.

PhoneGnome, developed by TelEvolution, is similar to IPW as it provides a POTS and a VoIP line. It has the advantage of being compatible with any SIP-based service and it acts as a gateway to other SIP providers. However, it cannot work with Skype and Vonage. This is because Skype uses a proprietary protocol and Vonage does not permit gateways to other VoIP providers. The PhoneGnome requires a separate power source but can work without a computer. It has two RJ11 ports for an incoming line and the handset and one RJ45 port for a broadband connection. However, the PhoneGnome requires a POTS line for initialization. The PhoneGnome is a standards-based service priced at $120 and includes features such as voicemail and email blocking. Its rates for calls to POTS lines are comparable to that of Skype.

IPv6

VoIP networks are increasingly being used by companies to avail enhanced functionalities such as unified messaging and increased mobility and savings on international calls. VoIP is being used for managing virtual contact centers as well.

However, the growth of VoIP is limited by the absence of inbuilt QoS in the IP networks that prevents it from offering levels of service that would be acceptable to the industry. The transfer of VoIP packets over firewalls is hampered due to network address translation (NAT) and protocol considerations. This issue, along with eavesdropping concerns, is being considered in the development of the new generation of VoIP networks. These networks will be based on IPv6 and will concentrate on providing scalability and industry-level reliability. This would enable VoIP networks to achieve the end-to-end interworking any time and any place, which is not possible currently.

IPv6 aims to offer a better solution to the NAT-related problems as compared to the NAT-based accommodation, which is the currently used solution. The complexity and cost overheads of the Internet and its applications increase due to NAT techniques.

IPv6 will facilitate expanded addressing, autoconfiguration, multicast, QoS, etc. IPv6 will also enable a more efficient use of IP addresses by creating a new format for the addresses. The addresses will be of 128-bit each and there will be approximately 3.4 x 10 raised to 38 addresses.

Wireless Office

Office Depot, Inc has launched a hosted Wireless Office Service for SMBs. The service enables communication with employees who are provided with an extension number based on a single business phone number. Wireless Office Service integrates the cell phones of the employees with the office phones, irrespective of the service providers.

The service is hosted by AccessLine Communications and a single voice-menu-driven number is used for routing the calls. The call is transferred to the employee using virtual phone numbers and can be accessed on any type of instrument. The service works like a virtual PBX for the SMBs without the cost or time involved in setting up an actual PBX. It has features such as integrated voice mail, find me/follow me, etc and can support up to 500 employees.

The SmartVoice service provided by AccessLine allows businesses to implement VoIP in an incremental manner. A gateway required to access the service is far easier to install as compared to the expense and effort involved in replacing the entire phone infrastructure. Since Wireless Office is an IP-based application placed on top of the currently used phone service, it provides the business with enhanced functionalities without having to shift to a full hosted VoIP solution.

A web-based management tool forwards all business calls to an employee’s voicemail after office hours. This helps the employee to keep his professional and personal life segregated. Information regarding the service rates can be obtained at the company web site.

Selecting a service provider

The first step to selecting the right service provider is to issue a Request for Information (RFI). This is followed by raising a matrix RFP. networkworld.com reports:

One of the ironies of the rapid pace of technical change is that companies often know more about how new technologies can meet their needs than the service providers offering them.

VoIP in government organizations

Even though revenue and competition are not the driving forces that government bodies are subject to, they too need to cut costs. Convergence of voice and data provides government bodies with the opportunity to reduce costs and reap the benefits of enhanced functionality.

Government networks run on highly efficient TDM networks that use the same compression algorithms as VoIP networks. The difference lies in the fact that unlike VoIP compression, TDM voice compression is not accompanied by any other overheads. VoIP calls do have the advantage of bandwidth savings due to silence suppression. According to studies as much as 62% of a voice call is silent.

In a TDM setup, the bandwidth is dedicated to a call at the beginning of a call. The IP overhead that leads to increased bandwidth and the reduction in bandwidth due to silence suppression evens out the bandwidth consumption in VoIP calls and makes it comparable to that of TDM calls. Frame packing is an effective technique used to reduce the header size of VoIP packets. It involves loading several frames of voice packet into an IP packet.

The frames can be loaded onto a single packet in two ways. One method is to add several voice frames from the same voice call. A drawback of this method is the limitation in terms of the number of voice frames that can be added; too high a number can lead to delay. Another method is to use voice frames from different calls that are taking place at a given time. This technique allows frames from 60 different calls to be present in the same packet.

By minimizing the extra bandwidth used due to the IP headers, the advantage of silence suppression is felt more keenly. The bandwidth utilization of VoIP calls reduces to half that of compressed TDM calls. However, the commercially used standards such as H.323 and SIP do not offer the facility of frame packing. A typical characteristic of voice traffic is the small size of the multitude of packets generated. 33 small packets of 50 bytes each can be generated every second with VoIP calls. In contrast, a data packet has a maximum MTU size of 1500 bytes.

In order to maintain the QoS of voice services, voice traffic is differentiated from data traffic by DiffServ. STU-III and STU-IIB are standards used by U.S government agencies and NATO respectively, for the purpose of securing voice communications. The voice call is transferred as encrypted data over a modem. Modem calls do not support speech compression and therefore PCM (64 Kbps) is used for transferring them. Use of differential waveform coding (ADPCM) can reduce this to 32 Kbps but it impacts the modem transfer rate.

The problem of maintaining bandwidth efficiency as well as the security of the call can be solved by not using ADPCM and terminating the modem signal at the entry to the network. By extracting and transferring only the modulated data from the signals by means of a Secure Call Relay, bandwidth consumption can be managed. A buffer can help smooth jitter to a large extent with a minor delay in traffic. However, this is not possible with secure modem calls as delayed signals can lead to the termination side reconstructing the data sent by the originating side in an incorrect manner.

Error correction is utilized for prompt correction of corrupt VoIP packets without retransmission. Error correction is particularly useful with secure calls. A satellite hop can introduce a 250 ms one-way delay in a voice call and a half-minute round trip delay. Delay also increases the chances of the secure modem not remaining in sync. If satellites, such as INMARSAT, are being used in the government voice network, a BRI data interface can be used to connect the satellite transmitter to the network equipment.

Implementing VoIP in government networks can often mean having to deal wit
