Abstract
The invention provides techniques for selecting, on a dynamic basis, an interworking function (IWF) that can modify a communication protocol to a particular format required by bridged terminal equipment in a communication system. The IWF can be selected to ensure compatibility between transmission bandwidth, coding and other format parameters of a call and the corresponding parameters of its destination terminal in the system. An IWF in accordance with the invention may be utilized to allow a user to bind to different terminals having different capabilities over the duration of a given call. An IWF in accordance with the invention may also be used to insert additional data, retrieved from a database of the switch, into a reverse portion of the call directed from the destination terminal to the source terminal. The invention can thus be used to ensure that the established bandwidth between the destination terminal and the source terminal is substantially bidirectionally symmetric.
