Music on Hold

From FreeSWITCH Wiki

Music on Hold (MOH) is not a central component, and is dependent on endpoints supporting it. Presently only SIP is supported through mod_sofia.

In the case of call waiting on a single line phone connected to an ATA, it works like this:

1. 2nd incoming call comes in
2. Phone plays call waiting beep
3. User hits flash button
4. ATA sends a SIP INVITE message to FreeSWITCH, and in the SDP it says "sendonly"
5. FreeSWITCH receives the SIP INVITE and plays the hold music (assuming correctly configured)
