QQ,<div><br></div><div>I don't see that FreeSWITCH is doing anything incorrect here. According to RFC3264, the offerer (FreeSWITCH) sends an SDP and in the case of RTP, the answerer (GRSIP Gateway) must use the payload type offered, even if the answerer uses a different payload type when it sends a telephone-event.</div>
<div><br></div><div><a href="http://tools.ietf.org/html/rfc3264#section-6.1">http://tools.ietf.org/html/rfc3264#section-6.1</a></div><div>Specifically near the end:</div><div><br></div><div>"<meta charset="utf-8"><span class="Apple-style-span" style="font-family: monospace; font-size: 16px; white-space: pre; ">In the case of RTP, it MUST use the payload type numbers</span><span class="Apple-style-span" style="font-size: 16px; font-family: Times; "><pre class="newpage" style="font-size: 1em; margin-top: 0px; margin-bottom: 0px; page-break-before: always; ">
from the offer, even if they differ from those in the answer."</pre></span><div><br></div>Technically, FreeSWITCH isn't "changing" anything anyway. The originator of the call (Vox Callcontrol) is the one who chose PT 101 in the INVITE that it sent to FreeSWITCH. FS is just passing that along without modifying it.</div>
<div><br></div><div>I think you need to contact the people running the gateway and make sure that they understand that they are not following RFC3264 if they're rejecting telephone-events in PT 101 simply because they prefer to send in PT 110. Also, if your Vox Callcontrol client has any configuration options then maybe you can tell it to use PT 110 for RFC2833 DTMFs. It is a bit of a workaround but this is SIP, so no one is expecting perfection. :)</div>
