Abstract
Telecommunications network components configured to manage call control of a communication session of user equipment are described herein. An anchoring network device may proxy signaling traffic for the communication session. The anchoring network device may determine a routing identifier based at least in part on which access network, or which type of access network, is carrying the communication session, and may transmit state information of the communication session to a call-control server in association with the routing identifier. The call-control server may provide control information of the communication session to the anchoring network device in response to the state information. The anchoring network device may modify the communication session, e.g., by adding or dropping one or more parties, in response to the control information. The routing identifier may be determined based at least in part on capabilities of a communication session indicated in a session-initiation message.
