No DTMF Feedback when on DTMF INFO
When I set my phone to use DTMF INFO instead of RFC2833, I don't get any audible feedback from the phone. I want to switch to INFO, but I can't since you don't get any audible feedback. You press a number and you can see the number on the screen, but the phone doesn't play it back. The DTMF itself works fine, we just need to be able to hear that a number was pressed.

RE: No DTMF Feedback when on DTMF INFO
Sorry but when you using the sip info, when you press the digit , the phone send the SIP INFO packet to the server, it won't exist the rtpevent packet, so the phone won't play the DTMF tone.
it is the normal behave , sorry for the inconvenient.
Best Regards!
