Play Background Music During call

Hello All

I need to play a Any Music file which I define when A and B party calls starts. Like when I send call to B party from A party the prompt which I define want to play it will play when they talk to each other

Help will be appreciated

My advices would be don’t, because it will cause you problems in complying with accessibility legislation and because, it will cause problems if any part of the phone circuit used a codec that is any more lossy than G.711, as most high compression codecs assume pure speech.

However, the typical ways of doing this are to use the whisper feature or maybe to use a conference.
