<br>
I am running opensips 2.1.1 and have a question regarding accessing <br>
failure_route.<br>
<br>
<br>
In case I send INVITE to some destination where I receive 3xx, 4xx or <br>
5xx reply, call goes to failure_route and uses next gw from there. <br>
Everything fine so far.<br>
But in some cases it hapens that opensips sends INVITE to a destination <br>
from where there is no reply.<br>
In this case opensips repeatedly sends INVITEs to that destination and <br>
doesn't do failover to failure_route.<br>
<br>
I played so far with $DLG_timeout variable, set to 2 sec.<br>
In this case opensips does failover to failure_route after 2 sec, <br>
however established call via next gw is also terminated after 2 sec.<br>
<br>
<br>
Is there another way to reach failure_route if remote end doesn't replay <br>
in expected time?<br>
<br>
