Which is great thank you very much.</div><div><br></div><div>But I have come across a couple of cases that are not working for me yet:</div><div><br></div><div><div>FAIL CASE 1 : It does not send the REFER to the from device when the from device is registered with transport UDP and with stun disabled.</div></div><div>FAIL CASE 2 : It does not send the REFER to the from device when the from device is registered with transport tcp with stun enabled. It turns out that the snom is not doing stun when the transport =tcp so this is actually the same case as the one above …. i.e. nat handling and routing.</div><div><br></div><div>… not sure yet whether the nat routing failures are is due to my script or the module… I would have thought theREFER should still go to 105@NATROUTERIP rather than 105@LANlocalIP?</div><div><br></div><div><br></div><div>WORKING CASE : udp transport, stun enabled</div><div>--------------------------------------------------------------The message buffer dump at the top of request_route() gives me</div><div><div style="margin: 0px;

<br>
should be fixed in 4.2 -- the issue was introduced when changed the
