When I have dtmf type set to rfc2833 and call my cell i can hear the tones.... I can call comcast and get through the IVR but when i call other people they can't hear my tones and some IVR systems won't register my dtmf at all...

I set it to inband and everyone can hear and im confident since the audio is going through it will work on any IVR i call

another issue is that no matter what settings with DTMF i have found so far nothing will make the number show on the screen properly, they always show as asterix (stars)

Any advice or guidance is greatly appreciated.
