An approach for providing content transmission upon placement of a call on
hold is disclosed. A data communications system includes a proxy server
that is configured to receive a message from a first client indicating
the hold condition of a Voice Over Internet Protocol (VOIP) call with a
second client. The system also includes a content server (e.g., music
server) that is configured to transmit the content stored therein to the
second client in response to a request message from the server.
