[SR-Users] LCR Failover

[Daniel W. Graham]

I was able to figure out why my logic didn't work. I was calling the default route(RELAY) in LCR route, since route(RELAY) has t_on_failure already specified, setting t_on_failure in LCR route did nothing.

I am now calling t_relay directly from LCR route and failure route is now working. I just need to tweak timers and make sure I do not need to call any other functions such as NATMANAGE that are specified in default route(RELAY).

Kamailio sends the following when the first gateway times out. Failure route is never executed and next_gw specified in route block still results in the following.

Asterisk placed call to kamailio:

U kamailio:5060 -> asterisk:5060
SIP/2.0 408 Request Timeout.
Via: SIP/2.0/UDP asterisk:5060;branch=z9hG4bK670647ee;rport=5060.

if t_relay fails and failure route is not executed, you should call next_gw in route block.
