Ixia IxVoice 3.10 tests VoIP and Packet over Cable

With today's news about Comcast getting in VoIP, the question is now, who isnt in VoIP? All cable companies, ILECS, CLECS, wireless providers. Basically everyone wants a piece of the pie. Talk about timing... Companies like Ixia that are updating their testing systems for packet data over cable are in a great position. Today, Ixia announced their IxVoice 3.10 testing system supports PSTN, VoIP, MGCP, COPS and SS7 and other related protocols. Here is a portion of the Ixia IxVoice 3.10 release: 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:o         New Telnet commands that can modify configuration files before runtime and then generate execution reports.  o         New Tcl script functions that allow the control external devices from within an IxVoice test scenario.  o         Ability to auto generate reports and email them to the specified recipientIxVoice 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 Ixias IxVoice, resulting in the most complete, flexible, and automated solution available for SIP telephony testing:o         SIP over TLS with associated encrypted RTP streaming for emulating endpoints over secure connections.o         New SDP editor/ interpreter within SIP and MGCP that facilitates positive and negative testing of media stream offers /answers.o         Additional codecs to accommodate a large number of DUTs o         Variable support in a SIP text editor for negative testing and the capability for sending custom SDP texto         XML parser that enables users to parse any XML extensions in the SIP messages
The complexity of VoIP, QoS, integration with the PSTN, etc means that testing systems such as these will play a vital roll in the successful deployment of VoIP.
