[OpenSIPS-Users] limiting the number of gateways tried in lcr module

[Brett Nemeroff]

I don't entirely remember the way the arming of the flags works and how they
persist across failure_routes. Maybe someone can comment on that?
Instead of using flags, call:
               $avp(i:500) = 1; # Initialize counter of failed attempts

from your main route block, before failure route is called.

Let us know how that works for you..
