I have Xfinity(comcast) and the phone suddenly stopped working in touch-tone mode. Press buttons but dial tone continues as if no buttons were pressed. Reconfigure phone to Pulse-Dial like the old rotary phones and it works fine. Of course in this mode I can’t get to my voicemail and it is very annoying to wait for the numbers to dial. I have replaced the phone and xfinity support is clueless and doesn’t even know that there is more than on dialing mode. I am not sure if this is a xfinity responsibility to auto recognize which dialing mode is being used or a gateway responsibility. Can anybody confirm?
If it is a gateway responsibility is there a configuration parameter or is it auto and simply failing now?
