Abstract
A system and method provide a call service features in response to call control information conveyed by a monitored bearer channel in a telecommunications network. A bearer channel monitor captures the call control information and relays the information to a call control application server. The call control application server analyzes the call control information, and provides call control instructions to a call control node that operates in the telecommunications network to effect the call service. The call control node serves as one or more virtual switching points in the network to directly control call routing without disconnecting a called or calling party, unless required as part of a service feature. Control from a center of the telecommunications network provides rapid and efficient call control without use of edge devices or duplication of bearer channels in the network.
