Telephony Services over Public Switched Telephone Network

Nine leading next generation telephony equipment and software vendors will unveil the most extensive, multi-vendor implementation of Internet Protocol (IP) telephony on Tuesday at the Spring 2000 Voice on the Net (VON) show, March 28-30. This interoperability demonstration proves the feasibility of next generation, multi-protocol networks with enhanced services.

Industry leaders Agilent Technologies, dynamicsoft, 8x8, Ericsson, NetSpeak, Pingtel, SALIX (recently acquired by Tellabs), telecom technologies and Vovida Networks are participating in the demonstration.

The demonstration shows enhanced IP telephony services across a multi-vendor network. The demonstration runs live enhanced packet-based telephony services between an IP network, using Session Initiation Protocol (SIP) and Media Gateway Control Protocol (MGCP), to the Public Switched Telephone Network (PSTN) using the Signaling System 7 (SS7) protocol.

8x8's Netergy Advanced Telephony System (ATS) is an iPBX, which interfaces to the SIP-controlled packet telephony network for long distance and PSTN access. The ATS incorporates the Netergy iPBX Server System, which controls multiple Netergy Media Hubs, CPE that adapt traditional phones to IP networks.

SIP calls from intelligent IP phones provided by PingTel are routed to the INtelligentIP softswitch and then to the PSTN and other SIP devices by dynamicsoft's SIP Proxy Server, while dynamicsoft's SIP Location Server provides user registration and location services.

A unified voice mail application is shown via Vovida Networks' telephony application server and audio conferencing is provided by Pingtel's intelligent SIP phone. Unified messaging and presence management are provided by Ericsson's iPulse(TM) application.

The NetSpeak SIP Webphone implements a SIP RFC 2543 compliant user agent, along with a full range of consumer and business-oriented Softphone features like multiple lines, automatic callback, call hold, call forward and transfer. Additionally, NetSpeak provides SIP network agent enabled server products.

telecom technologies inc.'s INtelligentIP(TM) softswitch provides the SIP/MGCP conversion to the SS7 interconnection, and all of the call control functions for the packet telephony network. MGCP is used to control the signaling between the softswitch and the SALIX ETX5000(TM) class independent enhanced telephony switch and Ericsson's 511 media gateway. The ETX5000 and the Ericsson 511, which provide seamless interconnection between the PSTN and packet networks, then connect to the global PSTN.

Agilent demonstrates the ability to test VoIP to the PSTN with its FASTest(R) Automation System product. The test system will provide automated, end-to-end service verification of this next-generation communications demonstration. All of the components in the test network conform to industry standard protocols for packet telephony, including MGCP and SIP.
