Yes, our configuration calls do_routing multiple times for different failover
cases. You may want to verify this but I believe that the additional calls will
append to the relevant AVPs used by the module, so if you haven’t routed to all
destinations, you may need to clear out the AVPs prior to calling it again. I’m
not positive on that part though; it may overwrite existing values.
We created a little helper route to do this:
route[clear_dr_avps]
{
avp_delete("$avp(dr_ruri)/g");
avp_delete("$avp(dr_gw_id)/g");
avp_delete("$avp(dr_gw_prfx)/g");
avp_delete("$avp(dr_rule_id)/g");
avp_delete("$avp(dr_rule_prfx)/g");
avp_delete("$avp(dr_carr_id)/g");
}

Subject: [OpenSIPS-Users] do_routing with failover to shorter prefix
Hi,
So I have this in my opensips.cfg
if ( !do_routing($(avp(drgID){s.int<http://s.int>}),,,,,$var(gw_attributes)) ) {
send_reply(404,"No Route found");
exit;
}
And I know that do_routing will match on the longer prefix on dr_rules table
first.
My question is
Now after failing on all the routes, can we still do another do_routing with
shorter prefix matching?
