<div dir="ltr">Hi Saúl,<div><br></div><div>I've heard back from eZuce. They say the problem is the contact is being modified with a transport parameter, and thus failing a match.</div><div><br></div><div>Specifically, the gruu contact obtained in one registration is "~~gr~ReZQUTUDuTi@<i><a href="http://sip.host.net">sip.host.net</a></i>;gr", but the contact returned in a call's 200 OK is "~~gr~ReZQUTUDuTi@<i><a href="http://sip.host.net">sip.host.net</a></i>;<u>transport=tcp</u>;gr".</div>
<div><br></div><div>The registration domain has a NAPTR record indicating equal weights for UDP and TCP SRV records. I force the registration to TCP with primary proxy value that includes ;transport=tcp. Maybe this is relevant, maybe it's not.</div>
<div><br></div><div>Anyway, their interpretation of the RFC is that, and I quote, "The UA must not modify the GRUU string."</div><div><br></div><div>Thoughts?</div><div><br></div><div><br></div><div>- Jeff</div>

</div>> It does what you say - it now uses the GRUU contact in the 180. The ACK from the originating side still doesn't make it through sipX (openUC, really). I'll open a ticket with educe.<br>
<br>
Thanks Jeff! Please keep me posted. I’ll merge the patch anyway, since it does make sense to send the correct contact header there too.<br>
<br>
