Spirent Debuts Integrated VoIP and PSTN Test System

Spirent Communications introduced a new Abacus3 system for both VoIP and traditional telephony testing. Specifically, Abacus3 tests analog, TDM, ISDN, VoIP and video devices and networks. It provides accurate measurements with synchronization between the VoIP and PSTN sides of the network, enabling testing of stand-alone gateways and sub-networks. Abacus3 tests the capacity, functionality, performance, quality of service, and interoperability of IP phones and PBXs; proxy and registration servers; Internetworking gateways; DNS and application servers; call accounting, voice messaging, and conferencing servers; switches and routers; media gateways; signaling gateways; and media gateway controllers (softswitches). It supports all the major VoIP protocols, including SIP, MGCP, H.323 and Megaco. It also supports real-time voice quality measurements using PESQ and PSQM.
