CALABASAS, Calif. -- Ixia (Nasdaq:XXIA - News), a leading, global provider of IP network testing solutions, announced today the latest release of IxVoice, its comprehensive analysis solution for converged telephony testing. This release of IxVoice introduces a number of significant enhancements to greatly improve and simplify the verification of packet data over cable solutions, including support for traditional PSTN and VoIP technologies and related protocols, such as MGCP, COPS, and SS7.

"Ixia's IxVoice test solution is targeted at the complex testing requirements of the telephony industry, including packet over cable manufacturers and those developing and testing the infrastructure of the core VoIP network," said Alan Amrod, vice president of marketing for Ixia. "IxVoice will facilitate a seamless transition from legacy telephone switches to a cost effective and utility grade VoIP network."

Ixia's IxVoice incorporates a Packet over Cable test suite that makes it possible for equipment manufacturers and cable operators to quickly verify conformance, performance, and interoperability of their solutions. The Packet over Cable test suite can emulate analog phones as well as the traffic from the CMTS devices, eliminating the costs associated with acquiring and managing a large test bed that traditionally would include thousands of cable modems and MTAs (Media Terminal Adapters).

IxVoice is able to fully automate Packet over Cable testing for call flow, feature verification, and performance analysis of voice networks in a scalable and distributed test framework. Key automation features in this release include:

  • New Telnet commands that can modify configuration files before runtime and then generate execution reports.

  • New Tcl script functions that allow the control of external devices from within an IxVoice test scenario.

  • Ability to autogenerate reports and email them to the specified recipient.

IxVoice also provides exhaustive functional and performance test capabilities, and support for legacy analog POTS, PSTN, and TDM interfaces, such as GR-303 and SS7, as well as support for the MGCP, COPS, SIP, and H.248/MEGACO protocols. In addition, a wide range of SIP features have been added to Ixia's IxVoice, resulting in the most complete, flexible, and automated solution available for SIP telephony testing:

  • SIP over TLS with associated encrypted RTP streaming for emulating endpoints over secure connections.

  • New SDP editor/interpreter within SIP and MGCP that facilitates positive and negative testing of media stream offers/answers.

  • Additional codecs to accommodate a large number of DUTs.

  • Variable support in a SIP text editor for negative testing and the capability for sending custom SDP text.

  • XML parser that enables users to parse any XML extensions in the SIP messages.
