Abstract
A method and apparatus for conducting a transfer of a conference call are disclosed. A media gateway receives a message to transfer a conference call from a first call resource to a second call resource. If the message indicates a change in the number of clients participating in the conference call, the media gateway simultaneously transfers the conference call and plays a prompt to the clients indicating the change. If the message does not indicate the change, the media gateway transfers the conference call in response to detecting a period of silence.
