If you do not need the music on hold, create the desired ringback tone as a sound file and install that in place of the moh sound. Because the moh sound repeats forever you only need to create a file long enough for the ringback tone and silence period. I do not know a method to change from moh to generated ringback because I am new to FreeSWITCH and still learning.

If a caller enters the queue, he/she is getting default moh sound. The sound is also playing when the call is passed to an agent and the phone is ringing. Is it possible to play a normal ringtone when a call is passed to an agent ? Thanks and best regards Stefan
