The # key is not handled any different than any other DTMF keys, so it has no reason to hang up your call. When you press it it just sends the corresponding key DTMF tone over RTP. I tested it and works just fine. You can test it yourself by calling echo at conference.sip2sip.info. It must be your IVR tree that interprets it in a way that makes the IVR tree close the call.

Yes, the # key itself. Why would you need a shortcut for a key press? Click the call in the sessions list and any DTMF key you press is sent to the other side as a DTMF tone.
