Abstract
A communication system, console, and method of patching a PTT call are provided. An audio stream and control messages are provided to the console, which patches the either or both to target devices. The identity of the audio stream source is embedded only in the audio stream. Initially, when the audio stream is first patched, the identity is not provided. While the audio stream is being patched, the identity is extracted and the control messages updated so that the identity is immediately relayed through the console without having to wait for the next periodic transmission of a control message from the console.
