Dear IBC,<br><br>with the bug "No Route" in 200 sent by GW, there are any workaround on opensips to fix that?

</div>First of all, I don't see the 200 arriving to caller in the SIP flow<br>
you pasted (probably because you just did the capture for one<br>
interface).<br>
<br>
Anyway I see a *bug* in the 200 sent by the GW: It doesn't contain<br>
"Route" header !!!<br>
It should include it since the INVITE arriving to it did contain "Record-Route".<br>
<br>
So, the 200 arrives to the caller with NO "Route" headers and the<br>
following Contact:<br>
<div class="im"> Contact: sip:SIPGW_PRIVATE_IP.<br>
<br>
</div>So, the caller would sent the ACK *directly* to SIPGW_PRIVATE_IP, and<br>
of course, it's unreachable from its LAN.<br>
<br>
The problem is in the GW which doesn't add "Route" header to the 200.<br>
This "Route" should mirror the value of the received "Record-Route"<br>
headers in the first INVITE.<br>
<br>
