Music on hold can be played to the callers waiting in the queue. When Music on hold is disabled, a ringtone will be played to the callers.

To play custom music, open the Actions menu in the queue extension, select Add music on hold and upload a mp3 or wav file. Multiple audio files can be uploaded. The Music on hold tab shows the playlist with the uploaded audio files. If more than one audio file is uploaded, the audio files will be played sequentially. When the end of the playlist is reached, it will start again from the beginning. To listen to an audio file press Play. To delete a file from the playlist press Delete.
