Spirent Communications introduced new VoIP performance emulation capabilities for Abacus 5000 IP Telephony Test System. The Abacus 5000 can emulate a call agent, signaling gateway, IP end-points, PSTN network elements and generate real voice and RTP packets. Spirent’s Abacus 5000 also features the first built-in media gateway controller (softswitch) emulator that can scale up to thousands of simultaneous calls. This feature simplifies testing of VoIP devices by reducing the need to deploy multiple softswitches and by saving time needed to configure and maintain scripts and test setups. Users also may synchronize results across PSTN and IP environments using a high bandwidth backplane. http://www.spirentcom.com

You just read about VoIP. Here is what it replaced:
POTS / PSTN served from 1876. What ultimately replaced it?
POTS / PSTN analog voice carried as a continuous electrical signal over a copper loop to a circuit-switched exchange, which set up an end-to-end dedicated path for the duration of the call. Its job passed to VoIP — but the problem it solved, and the ideas it proved, live on in what replaced it. The standard rests here in the archive. One of 198 technologies here that opened a door and then held it for the next.
