Hi folks<div><br></div><div>I have the joy of talking to a Cisco device which behaves in weird and wonderful ways.
</div><div><br></div><div>When transferring a caller (in this case FreeSWITCH) to MOH it negotiates RFC2833 out of the SDP.</div><div><br></div><div>When reconnecting the caller to a more meaningful endpoint, it renegotiates the media again, but using delayed offer/answer, which means FreeSWITCH must perform the offer.</div>
<div><br></div><div>Since FreeSWITCH has seen RFC2833 removed previously:</div><div><br></div><div>    [DEBUG] sofia_glue.c:5277 No 2833 in SDP. Disable 2833 dtmf and switch to INFO.</div><div><br></div><div>It does not offer RFC2833 in the new SDP (if it did, the Cisco would now accept it and answer with it).</div>
<div><br></div><div>Any suggestion for how I can force it to re-offer RFC2833?</div><div><br></div><div>Regards,</div><div>Richard</div>
