摘要 A method and apparatus for providing a hold termination message service in a communications network. An on-hold telephone call between a hold initiating party and a holding party is monitored at a network node for a hold termination signal, such as a DTMF signal, from the holding party. A hold termination message can be recorded when the hold termination signal is detected. The hold termination message is then delivered from the network node to the hold initiating party.
