First Claim
Patent Images
1. A communication node for connecting and maintaining a call session between a caller device and a callee device, the communication node comprising:
- a session controller module adapted to interpose itself between the caller device and callee device through a whole duration of the call session there between; and
a plurality of internal Session Initiation Protocol User Agent (SIP UA) servers, each of the internal SIP UA servers being adapted to communicate with the session controller module by open protocol for providing at least one service during the call session.

Abstract
The present invention relates to a communication node and method for connecting and maintaining a call between a caller device and a callee device. The communication node comprises a session controller module and a plurality of internal SIP UA (Session Initiation Protocol User Agent) servers. The session controller module is adapted to remain in communication with the caller device and the callee device through a whole duration of the call. The plurality of internal SIP UA servers is adapted to communicate with the session controller module by open protocol.
