[OpenSIPS-Users] Timer Based Failover Question

[Dave Singer]

I ran into the same problem with one of our carriers. The way I did it, with
advice from bogdan, was to set the fr_inv_timer_avp to 6 sec (so long
because of some calls to cell phone systems have long delays) when sending
to the particular carrier then in a reply route special to that carrier,
reset it to the normal 300 if the response was a 18x. Here are
the pertinent parts:

modparam("tm", "fr_inv_timer", 300)             # Timer on Final response:
Minimum is 2 sec, Default is 120 sec.
modparam("tm", "restart_fr_on_each_reply", 1)   # Reset fr_int_timer on each
reply. Needed if you want to adjust the fr_inv_timer_avp with avp depending
on reply.
modparam("tm", "fr_inv_timer_avp", "$avp(i:2)") # Used if overide of
fr_inv_timer param is needed.
modparam("tm", "onreply_avp_mode", 1)           # set to 1 if you want to
access and or save avps from or for other parts of the transaction, like
changing the fr_inv_timer_avp.

route[carrier_c] {
        if (is_method("INVITE")) {
                t_on_failure("2");
                t_on_reply("2");
                $avp(i:2) = 6;
        }
}
onreply_route[2] {
        /* once we get ring progress let it ring for upto 300 sec */
        fix_nated_contact();
        if ( $rs =~ "18." ) {
                $avp(i:2) = 300;
                #xlog("got ringing, reset final timer to $avp(i:2) sec.\n");
        }
}
