<blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex">Hi 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"><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"><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"><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>
