XLite/Bria DTMF Input Not Recognized

I am having trouble with the DTMF input on XLite and Bria softphones. Whenever a button is pressed asterisk shows a warning “unknown rtp codec 126 received…” and does not recognize DTMF. I have tried setting it to RFC2833 and Inband in the softphones but no difference. Softphones work on some computers and on others they don’t.

All your help is highly appreciated.

I fixed it myself, but its strange. I just plugged in a headset with Microphone and Bria is just fine. No more “Unknown coded 126” warnings in Asterisk and the DTMF is being recognized too. Isn’t it strange :smile:
