Re: [pjsip] Remote does not support RFC 2833

It seems to be the proxy that doesn't support RFC2833, no telephony
rtpmap in the received 200 OK answer. As you mentioned previously both
parties are pjsua, so DTMF should be sent/received smoothly (you can
try direct call without proxy to test this). Or if the proxy actually
supports RFC2833 then it may be configured incorrectly to do so.
