System and method for releasing media streams from a communication server

摘要

A first call leg is established between a first communication device and a communication server having a telephony controller for controlling a hardware media processor. A second call leg is established between a second communication device and the communication server. The first and second call legs carry a media stream between the first and second communication devices, and the media stream is initially intended for processing by the hardware media processor. A suitable condition is needed to transfer the media stream to a release server. When the suitable condition is not detected, the media stream is processed with the hardware media processor. When the suitable condition is detected, the media stream is transferred to the release server. The release server lacks a hardware media processor.

1. A method, comprising:
establishing a first call leg between a first communication device and a communication server having a telephony controller for controlling a hardware media processor; establishing a second call leg between a second communication device and the communication server, the first and second call legs for carrying a media stream between the first and second communication devices, the media stream initially intended for processing by the hardware media processor; determining that processing the media stream initially does not require use of the hardware media processor; transferring the media stream from the communication server to a release server for processing based at least in part on determining that processing the media stream initially does not require use of the hardware media; while the media stream is being processed by the release server, determining that processing the media stream now requires use of the hardware media processor, comprising detecting a signal that represents a functionality of the hardware media processor that the release server lacks; and in response to determining that processing the media stream now requires use of the hardware media processor, transferring the media stream from the release server back to the communication server.
