Ok, that makes a little more sense to me. However, OpenSIPs isn't relaying it to the public IP which is in the RURI of the BYE, it's sending it to the private IP on OpenSIPs. Is that because of the Route Header? <br>
<br>So this seriously looks like a proivder problem not adhering to standards? Is there anythign I can do on my side to make it play nice?<br> I'm not sure I can get this provider to change anything .<br><br>-Brett<br>

<br>
</div>No, that's not correct, the RURI of the BYE from provider *MUST* be<br>
the same as the RURI in the INVITE Contact the provider received.<br>
The BYE is sent back to the public IP, of course, but it's routed<br>
thanks to "Route" header (loose route).<br>
<br>
This is the INVITE OpenSIPS sends to the provider:<br>

<br>
<br>
</div>As you can see:<br>
1) The BYE is sent to the the address in top Route (loose route) -> OK<br>
2) The BYE RURI address is <a href="http://62.175.182.141:5060" target="_blank">62.175.182.141:5060</a> while INVITE Contact is<br>
<a href="http://10.10.67.190" target="_blank">10.10.67.190</a> -> ERROR<br>
3) I really wonder why the BYE contains a useless Record-Route.<br>
<br>
The behaviour in OpenSIPS is correct. The provider creates a wrong<br>
in-dialog request (BYE) since it should be:<br>
BYE <a href="http://sip:15125551234@10.10.67.190:5060" target="_blank">sip:15125551234@10.10.67.190:5060</a> SIP/2.0<br>
