    I have 3cx iphone app version 1.1.5. The DTMF tones do not register. I do not see anywhere in the 3cx settings where you can change dtmf. My voip provider is Viatalk and I have called them but they don't have an answer. Curiously enough, when I call their customer support the dtmf tones register. Every other place I call the tones are unrecognized. I have also installed the 3cx tunnel iphone app but that does not seem to work with an outside voip provider. (or I do not know what settings to input.) Any help would be much appreciated.

    the 3CXPhone sends DTMF as RFC2833 and not inband as a tone. so the equipment on the other site must understand this...
