Music on Hold


As of this writing there is no one standard for supporting music on hold with a pure SIP phone system. Polycom and snom phones are known to support the same Music on Hold service IETF draft that Sipfoundry chose to support in sipXecs.

To change the Music on Hold audio, from the System Administration page, click on the Features menu and select the Music on Hold menu item. The following page will be displayed where the administrator can select a WAV file already present on the system or click on the Browse button to select a WAV file on his/her local computer.

Clicking the Apply button activates any change to Music on Hold.

Each call placed on hold will hear its own instance of the music on hold audio file starting from the beginning of the file.
