Providing The Audio Source

To upload a music (sound) file :
Upload the file using the Uploading a Sound File procedure in Configuring the Media System.

To connect a live audio source through an FXS port:

Connecting an audio source for Music On Hold requires the use of an adapter betweenSBC Edge RJ11 port and the source device (CD player, radio, iPod. MP3 player, personal computer, etc.). Common adapters include a 3.5mm connector on one end and an RJ11 on the other with an isolation transformer between the two.

Music On Hold volume is controlled from the audio source device (iPod, MP3 Player, etc.). The preferred volume level can be adjusted by listening to the stream, or by examining the RTP trace captured from the SIP call leg of the call. Use the receive gain settings on the FXS port to make any additional fine-tuning volume adjustments.

Selecting the Music-on-Hold Mode

To use Music on Hold, you must specify a source in the Media System Configuration page of the UI and then Enable Music on Hold in the applicable SIP Signaling Group.

Verifying Music Upload Status and FXS Music-on-Hold source.

To verify that the file has been successfully uploaded:

  1. In the WebUI, click the Settings tab.
  2. In the left navigation pane, go to System > DSPs

The Music on Hold status will be Loaded if the file was successfully uploaded.

Note:

If your system does not have transcoding licenses, be sure your MOH file is encoded in the same Law as your calls use. For instance, if you're using A-Law for your calls, be sure to use an A-law encoded MOH file.

If your system has transcoding licenses, then the system will automatically transcode between different types of codec compressions.
