ABSTRACT:
One or more elements in a telecommunications network (10, 10′and10″) receive a call hold-initiating message when a first party places a second party to the call on hold, and in doing so, triggers a call hold event in the network. In response to the call hold-initiating message, the network element may take one or more actions, including releasing one or more network resources and/or providing a service to the second party during the period the call remains on hold. Upon resumption of the call, the network will re-acquire the resources that had been previously released.
