Music on Hold

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. Second 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).
