Programmatically determine when an outgoing call starts to answer a call (calls another person)

I want to know how to detect in android when an outgoing call is acceptable (but not yet accepted) by another person and you receive a callback tone.

I tried PhoneStateListener

using the method onCallStateChanged(int state, String callingNumber)

, but the state is only returned to me 2

(starts) and 0

(ends), not when the call is acceptable by the other person (there is a time between you the call starts and the other phone takes the call and starts ringing)

Is there already an android method to know it or what to do?
