Here is a code snippet to trigger an answer for the incoming call:

private void answerPhoneAidl(Context context) throws Exception {
// Set up communication with the telephony service (thanks to Tedd's Droid Tools!)
TelephonyManager tm = (TelephonyManager) getSystemService(TELEPHONY_SERVICE);
Class c = Class.forName(tm.getClass().getName());
Method m = c.getDeclaredMethod("getITelephony");
m.setAccessible(true);
ITelephony telephonyService;
telephonyService = (ITelephony)m.invoke(tm);
// Silence the ringer and answer the call!
telephonyService.silenceRinger();
telephonyService.answerRingingCall();
}
