Receive DTFM code in android phone?

Question

I want to receive DTFM code in Android which is sent by the caller. Is it possible?

Answer 1

This is not possible through the phone, as you have no access to the underlying telephony hardware. The only way that telephony hardware is accessed in Android is through the Radio Interface Layer (RIL). The frequent trick to play, is to force the user to play their call through the speaker, for which you see some apps exist that will do this.
