Is it possible to play a music during a phone conversation where receiver and call

Answer 1

Two answers, both valid, depending on how sloppy you like to be:

1) No, it's not currently possible to inject audio into a phone conversation.

2) Yes, it's possible. It's also an ugly, ugly kludge. Turn on the hands free function of your phone. Create a media player, set the media source, set the volume to 1.0f (highest) and call player.start(). If the microphone and speakers on the phone are of reasonable quality, the other party to the call will hear the music. He or she will also continue to hear anything you say, as well as ambient and other sounds in your immediate vicinity.
