by using gsm call the feature you want doesn't have any api support. But you can try any of the following

Case 1:

when a number key is pressed during call then a dtmf tone is send. try if you can somehow decode the dtmf tone. As there is no recording option in android during call you can try setting speakerphone on.. ( i haven't tried this, so not sure fully) For this you can see this project

Case 2

Create another channel over network. create server client mechanism to register each number in your server. whenever two calls of two registered users are made send data over network. you can see a similar apps thruto
