We run Call Manager 4.13 and I have a group of operators running Attendant Console.
What is the best way to replace the MOH while the call is being routed to the operator with a ringback sound?
You can change the MOH audio source.
Place your .mp3 / .wav files on the location given below:
Now go to callmanager administration web page
Service ---- Media Resource ---- Music On Hold Audio Source
Now you can see the file you droped in the " MOH Audio Source File * " field.
