    For all 3CX VoIP Client users, DTMF tones are not working correctly. Desk phone DTMF works perfectly. I've tried all three methods of sending DTMF(payload, in-band, SIPINFO) and can't get any to work. The payload option works the best however is sends two sequential tones with every key press (press 2, receiver gets 22). Of course this only happens on external dialed calls. Has anyone found a solution that works?
