Is the screen that comes up as the call is ringing part of the Dialer App or a part of the firmware or OS? I ask because I flashed Cm7 (Gingerbread 2.3.4) and I am having difficulty with the stock dialer when calling an automated attendant where you then enter numbers on the dailer keypad. I downloaded TouchPal Dialer App and it works until it rings and then I get the same screen as I got with the stock dialer and have the same issues. The attendant does not properly recognize the numbers as they are entered. I have tried to find info on making the new dialer my "default" dialer, but as yet have not found anything useful. Any help or ideas appreciated.
