Alcatel Supplies SIP for BT

Alcatel is extending the functionality and capacity of the Alcatel 5020 Softswitch and the ACME Packet Session Director (SD) already in commercial operation in BT's network. As the overall SIP session control element and mediation device among multimedia application servers, the Alcatel 5020 Softswitch implements the call & session control function (CSCF). The ACME Packet SD provides a proxy function (P-CSCF) to satisfy critical security and quality assurance requirements for carrier class IP multimedia services.


Alcatel said this IMS-compliant expansion plays a part in enabling BT to host a complete set of advanced revenue-generating voice and multimedia services over a common, open and reusable architecture. The expansion will be "live" in the BT network by the fourth quarter 2005.
