IP Telephony news wrap-up for Dec 18 – 2006

Telchemy has introduced DVQattest/EN, an active test tool for VoIP, IP videoconferencing and HD telepresence service assurance. The new product uses the company’s VQmon technology to provide network assessment, pre-deployment testing, SLA monitoring and advanced network troubleshooting for enterprise networks.

DVQattest/EN is a software agent that can generate 200 concurrent VoIP streams, 20 concurrent high definition 1080p simulated IP video streams and a range of network diagnostic tests, with an application for configuration and reporting.

In pre-deployment test mode, the software generates VoIP and IP Video streams that closely match actual traffic. In SLA monitoring mode, the tool generates occasional test calls that have minimal effect on the network but allow accurate measurement of service levels. For network troubleshooting, it generates short active test sequences that help to diagnose typical Ethernet, switch and router problems.

Telchemyís VQmon/SA-VM video analysis technology reports TVQM video quality metrics, including MOS-V, MOS-AV, I/ P/ B frame statistics and other diagnostic data. It monitors the quality of IP video streams, which can be unidirectional or bidirectional, with programmable image size, frame rate, GoP structure and codec type. For VoIP, DVQattest/EN uses Telchemyís VQmon/SA technology to analyze and report listening and conversational quality MOS scores and a wide range of diagnostic data.

DVQattest/EN is available as software for license to OEMs and network equipment vendors.

TeleGeography, which offers a VoIP market tracking subscription-based service, has released new findings from a study of the U.S. consumer VoIP market. The study, which includes both forecasts and survey results, reveals that national subscriptions will grow from 5.5 million at the start of 2006 to 23.7 million in 2010, with annual service revenues growing from $2.6 billion to $8.1 billion. From the beginning of this year to now, the firm finds that new weekly subscriptions have risen from 100,000 to 150,000. As VoIP grows over the next 5 years, LEC subscriptions are expected to drop 22%, representing a loss of $18.2 billion in revenue.

Based on TeleGeography’s survey, traditional telephone custoemers are more likely to subscribe to an incumbent’s voice offering and younger, more tech savvy customers are more likely to subscribe to a service offered by an independent, pure-play provider like Vonage or SunRocket. The firm believes the trend bodes well for the independents considering the youth are the future of the marketplace.

In an interesting survey finding, the firm indicated that nearly 20% of respondents had, at some time, downloaded and used a PC to PC or PC to phone based phone client.

Plantronics has introduced SupraPlus Wideband, a headset operational with wideband IP phones supplied by Avaya, Cisco, Nortel, Siemens and ShoreTel. The company has also introduced Vista M22, a Clearline audio amplifier, a call quality solution that works with both narrowband and wideband phones. The amplifier reduces audio problems originating from repeats, errors and listening fatigue as well as reducing noise, equalizing call volume and managing echo.

A monoaural version of the headset is available for $107. A binaural version goes for $132. The amp is $120.

The IMS Forum will host Plugfest at the University of New Hampshire Interoperability Lab in Durham from January 15-19. The event is held to test interoperability of various networking technologies among different vendors. Vendors participate under a single test plan. All results are private and covered by corporate and individual NDAs.

Ultimately, the organization hopes to be certify IMS services.

ViaTalk, an independent U.S. phone to phone service provider, has launched a promotional offer that includes 5100 minutes of North American calling per month for 2 years for $320. Like other providers, the ToS is loaded with unreasonable penalties such as a $5 fee for not returning the CPE’s original box before service cancellation.

SoliCall has introduced a free beta version of software that reduces background noise for calls using Skype or or popular VoIM services. The technology, based on proprietary algorithms, also provides record and functionality with the services.

GlobalTouch Telecom has deployed Cantata Technology’s IMG 1010 media and gateway server into its global network for the purpose of providing ISDN/SS7 functionality and connectivity to the PSTN.
