Music on hold

Music on hold is what callers hear while they wait — parked, held, in a queue, or on a conference bridge. Exovo plays it from a system-wide library you manage in one place.

Managing tracks

Admin → System → Music on Hold. The Music Files tab has ten numbered slots; for each, Upload a .wav or .mp3 track (WAV as PCM, 8 kHz, 16-bit, mono, up to 10 MB each) or Clear it. FreeSWITCH plays every uploaded track. Uploads and removals don't take effect until you press Save.

Under Playback Options:

• Randomize playback — shuffle the track order instead of playing through in sequence.
• Randomize per call — give each caller a different random order.

Playlists

The Playlists tab groups tracks into named sets, each backed by its own audio stream with a per-playlist Volume, Auto Gain and Shuffle. Add a playlist, name it, add its WAV/MP3 files, and it becomes selectable as a hold-music source — handy when you want different music for a sales queue than for the front-desk park.

Where it's used

The hold-music selection appears wherever a caller can be made to wait:

• Call parking — the music a parked caller hears (Admin → System → Call Parking).
• Call queues — per-queue hold music, under the queue's Voicemail & Messages.
• Held calls and conference bridges.

Each of these pickers also offers System music on hold — the default stream — so a queue or park falls back to it cleanly when you haven't chosen a specific track or playlist.
