Spirent Communications rolled out a new bundle of Convergence Test & Measurement applications for the Abacus 5000 IP Telephony Test Migration System. The new features add SIP, H.323, MEGACO, MGCP, and SIGTRAN protocol conformance. Spirent’s Abacus 5000 system provides a variety of test scenarios and unique capabilities, such as emulating a call agent (media gateway controller) and signaling gateway, the backbone of a VoIP network. By generating real voice and data traffic and Real-time Transport Protocol (RTP) packets, the Abacus 5000 with CTM-5000 tests interoperability among different equipment manufacturers and devices, allowing customers to easily pinpoint failures before new VoIP networks and services are deployed. http://www.spirentcom.com
