When I was testing my dispatcher setup with sipp, I noticed after a
number of calls go through, failure_route will get called, even though
I have a generous timeout value and the gateways are under no
significant load.
In my manual, (with phone) tests, the dispatcher never encountered the
problem (until I had a live number on, and many calls went through), so
perhaps it is more related to the speed of calls coming in...
I had the failure_route mark the gateway inactive so I would no as soon
as it occurred... a good number of calls went through before the problem
was encountered.

^^That was the first time failure_route was called...
I even commented out my alert script, in case it was screwing up
openSER... no difference.
Is there something wrong with my routing script?
