You can use a service to play music in the background. I'm not sure how it will be heard on the other side.

I don't think that you can mute the microphone.

does anyone have a sample on how to play a wav file over a phone call?

You can use backup tool to get the apk. then you can extract the code and have a look at the java-code. Or you find such functionality in a java-library and maybe some one will make a b4a wrapper for it
