<tt>Hmm, maybe I've not explained this scenario properly.<br>
<br>
The proxy that is sitting on the customer premises is calling via
our proxy. I dont have access to the customer's proxy at all. <br>
<br>
When their invite (via their proxy) hits our proxy the issue I
explained originally is encountered. I believe they are only
running a pure sip proxy, be it kamailio/opensips etc, and their
ua's point to it for registration etc. When making a call it
appears to just relay the invite but inserts a record route for
their proxy. This causes issues with our b2b when it generates the
bye message.<br>
<br>
I doubt stun/turn/rtpengine will help me in this scenario, unless
I'm misunderstanding you.<br>
<br>
Will kamailio not honour the recieved/rport parameters in the
route-header?<br>

All,<br>
<br>
I've come accros a scenario where a proxy is sitting
on a private <br>
address range and inserts a record-route specifying
the the private address.<br>
<br>
This causes issues whereby the BYE to an INVITE
attempts to relay to the <br>
private address defined in record-route.<br>
<br>
I was wondering, if we were inject a received and
rport parameter into <br>
the record-route header of the original invite, whould
kamailio relay <br>
the response (BYE) to the receive/rport destination
instead of the uri <br>
defined in the record-route header.<br>
<br>
As an example, initial invite comes in with a
record-route as follows:<br>
<br>
Record-Route: <a
class="m_-4293252755143832784m_2739383449457061252moz-txt-link-rfc2396E"
rel="noreferrer noreferrer" moz-do-not-send="true"><sip:172.17.0.2:5062;lr;ftag=b4551d29></a><br>
<br>
If we injected received and rport as follows:<br>
<br>
Record-Route: <br>
<a
class="m_-4293252755143832784m_2739383449457061252moz-txt-link-rfc2396E"
rel="noreferrer noreferrer" moz-do-not-send="true"><sip:172.17.0.2:5062;lr;ftag=b4551d29;rport=33429;received=212.172.2.212></a><br>
<br>
and relayed the message to the B2B.<br>
<br>
Then, I assume, when the B2B creates its BYE message,
the Route header <br>
should look like this:<br>
<br>
Route: <br>
<a
class="m_-4293252755143832784m_2739383449457061252moz-txt-link-rfc2396E"
rel="noreferrer noreferrer" moz-do-not-send="true"><sip:172.17.0.2:5062;lr;ftag=b4551d29;rport=33429;received=212.172.2.212></a><br>
<br>
Once this hits the kamailio instance to relay to the
last route header <br>
as mentioned above, would it set $du to received:rport
like it does with <br>
Via headers?<br>
<br>
Thanks<br>
