Communications software and solutions provider Telcordia Technologies, Inc. announced that the Telcordia Softswitch is now available with session initiation protocol (IP) application programming interfaces (APIs) to enable carriers to deploy new services and applications. The Telcordia Call Agent, a Class 5 softswitch, provides voice services over Internet Protocol (IP) and Asynchronous Transfer Mode (ATM) networks.

The enhanced Telcordia Call Agent will initially support SIP-based applications for emerging PC to PSTN and PSTN to PC applications. The release supports third-party call control applications for PC control of telephone features such as directory features, calling name delivery and call initiation. In addition, third party call control can be initiated from Internet servers for Click-to-Dial applications and from wireless PDAs. Future releases of SIP-enabled softswitches will include support for SIP-T to enable softswitch-to-softswitch handoffs and support for SIP-enabled Application Servers.

In addition to SIP support, the release includes new features for:

* ISDN PRI Support

* Support for a CALEA Server

* Enhanced Operator Service Access Features (busy line verification, transfer to 911)

* Enhanced Operations Features

The Call Agent provides primary line VoIP and VoATM without the need for a Class 5 circuit switch. It works with the Telcordia associate-provided IP or ATM gateways to perform call control functions and deliver revenue-generating services running over IP and ATM networks.
