Music on hold files are used when a call is put on hold or parked. Whilst there are default sounds which come with your SmartPABX, like with the systems sounds you may upload your own custom recordings.
System sounds may be stored as either an MP3 or a WAV file but it is highly recommended that you use a similar quality and length of sound files as you would with your system sounds. All Music On Hold sounds are saved on your SmartPABX system.
Music On Hold can also group files together. This is useful for if you need to use specific sound files for different queues, or if you wish to set a specific music on hold group as the wait music for an IVR. In order to add a new group, press the Add Group button and choose a name for the new group. Within this new group, which you can navigate to by selecting that group from the drop-down menu of groups, you can upload sounds, or edit and delete them as with the default group. If you wish to delete a music on hold group, simply press the Delete button whilst on the page for that group.
