Android In-call Audio

Is this possible in android ?

I have tried all options

thanks in advance !!!

Are you trying to create some kind of voicemail app? That would be hard... Since most phones aren't capable of recording calls.

Anyway - to your question: Put the phone on speaker mode and play a recording using MediaPlayer. That's the only way I know of that will work on ALL phones...
