ipVerse to Integrate MIND’s CC&B Technology
ipVerse reported that it is planning to integrate MIND CTI’s customer care and billing solution, MIND-iPhonEX, with its IP telephony technology, ControlSwitch, to offer a softswitch based VoIP solution with integrated billing and customer care capabilities.

The iPhonEX technology is designed to provide billing and call traffic analysis for IP services such as VoIP. It features web interfaces for providers and subscribers that can be used to register, verify credit cards and perform a variety of other customer care functions. The product also provides support for call management, traffic analysis, fraud detection and convergent IP services billing capabilities.

The multi-protocol ControlSwitch call control system provides interoperability via SS7, MGCP, H.323, IPDC, SIP and ISDN-PRI signaling. It can support voice/data traffic exchange within or between provider’s networks. In addition, it can support more than one million busy hour call attempts, and it employs web based tools and an XML language to enable services to be developed without interrupting existing services.



LG Electronics to Integrate Net2Phone’s VoIP Technology
LG Electronics said that it is planning to integrate Net2Phone’s VoIP technologies into its VoIP gateway offerings. The LG gateway is a compact system that enables small to medium size corporations to route voice and fax communications over the Internet. The integrated solution will enable users to access Net2Phone’s VoIP networks to place calls from a PC or traditional telephone to any PC or traditional telephone in the world.

Net2Phone offers connectivity between PCs, phones, web sites and facsimile machines or any combination thereof. It can route calls to any telephone or PC in the world via its network of POPs.

ShelCad to Integrate Trillium’s H.323 Protocol Software
ShelCad reported that it is integrating Trillium Digital Systems’ H.323 protocol stack technology into the IP adapter device, Appearion, that it is developing to enable traditional phones to be used for IP telephony. The H.323 software technology enables OEM developers to design carrier class systems. It consists of H.225 RAS, H.225 call signaling, H.245 control signaling, ASN.1 Encoder/Decoder-PER TCP/UDP convergence and RTP/RTCP source-code software implementations. It has also recently been enhanced to support H.323 v3 technologies, Annex E for reduced call setup roundtrip time, H.450 support for deployment and supplementary services, and endpoint RAS APIs for both flexibility and interoperability. The vendor is also further developing the software to include support for Annex G, Annex M as well as fault-tolerant/high-availability support for increased network reliability.

Tolly Research Results
Low-Bit-Rate Voice Encoder Gets VoIP Nod: Tests Reveal Lucent Gateway Generates Acceptable Voice Quality Even at Low Speeds

By Charles Bruno, Executive Editor, Tolly Research

Network executives faced with the decision to deploy voice over IP technology in their enterprise networks must take solace from the fact that the products they acquire are capable of providing a degree of voice quality acceptable for business use.

Researchers for ITclarity, the industry’s leading source of hands-on testing of emerging technologies, recently tested a standards-based voice encoder (vocoder) for transmission of multimedia over extremely low-bit-rate connections that still provides acceptable quality audio for business applications.

Engineers measured the voice quality of Lucent Technologies’ implementation of a G.723 vocoder; G.723 is an ITU-T recommendation that specifies algorithms for a dual-rate vocoder originally designed for low bit-rate multimedia transmissions at either 6.3 kbps or 5.3 kbps. Both rates employ a Code-Excited Linear Prediction (CELP) algorithm; the difference between the rates is based on the excitation technique (Multipulse Maximum Likelihood Quantization, or MP-MLQ, for 6.3 kbps and an algebraic code for 5.3 kbps).

Voice-quality measurements were conducted for two different signaling methods, Integrated Services Digital Network (ISDN) Primary Rate Interface (PRI) and T1 robbed-bit, to determine the impact on perceived voice quality. ISDN PRI uses a single out-of-band common channel for signaling separate information channels. In contrast, T1 robbed-bit signaling uses selective in-band bits to provide signaling, thereby reducing the 64-kbps bandwidth available for voice to 56 kbps. Each of these signaling methods was tested in combination with the two vocoders we examined.

Voice quality was quantified objectively using the Perceptual Speech Quality Measure (PSQM), which provides, according to the ITU-T, the most accurate estimate of the subjective quality of coded speech (ITU-T Recommendation P.861).

Engineers determined that the G.723.1 vocoder, as implemented in Lucent’s MAX VoIP gateway products, does not provide voice quality on par with vocoders that support the G.728 and G.729 specifications for encoding speed for transmission over 16 kbps and 8 kbps connections. And, voice quality was notably different that earlier tests of a G.711 vocoder, which handles uncompressed voice over a 64 kbps circuit. However, voice quality over the low-bit-rate vocoders is still acceptable for business use.

Moreover, engineers found there is virtually no difference in voice quality when directing the encoder traffic over ISDN PRI lines or T1 circuits that employ robbed bit signaling.
