I am having issues with LCR failure route. I have two gateways specified in LCR table, if I change the address of the gateway with highest priority to a bogus IP, the failure route never seems to takes place and call is never routed to second gateway.

Also, I have tested successful calls to both gateways by switching the priorities around.

Here is what I receive after the first gateway times out:

U kamailio:5060 -> asterisk:5060

SIP/2.0 408 Request Timeout.
