<div dir="ltr">I have several carriers, and I use:<div><action application="set" data="continue_on_fail=true"/></div><div>... so I was a little surprised to see that a call that ended with NORMAL_TEMPORARY_FAILURE didn't route advance.</div><div>I dug into the PCAPs of this and comparable, and the only difference I noticed was that the ones that worked were invite -> 100 and then 503 NORMAL_TEMPORARY_FAILURE and the one that didn't work was invite -> 100, 183, and then 503.</div><div><br></div><div>I have a lua script that told me:</div><div><br></div><div><div>session:getVariable("originate_disposition") = SUCCESS </div><div>session:getVariable("bridge_hangup_cause") = NORMAL_TEMPORARY_FAILURE </div></div><div><br></div><div>so... I'm guessing that a 183 marks the originate as a success which is why continue_on_fail didn't work, since it wasn't a fail.</div><div><br></div><div>Is this expected? Is the carrier "doing something wrong" here?</div><div><br></div><div>They did helpfully send: "SIP/2.0 503 Service Unavailable - Route Advance"</div><div>More importantly: how can I fix it?</div><div><br></div><div>Thanks,</div><div><br><div><div class="gmail_signature"><div dir="ltr">-Avi Marcus<br>BestFone</div></div></div>
