Thank you Klaus for the suggestions. I've implemented the
configuration below. When the first t_relay fails, Kamailio generates
the 408 Request Timeout and doesn't attempt to try an INVITE to the
second address. This what the syslog says:
Nov 28 06:11:13 server kamailio[1315]: Attempting Carrier 1
Nov 28 06:11:28 server kamailio[1323]: Attempting Carrier 2
Nov 28 06:11:28 server kamailio[1323]: ERROR:tm:t_forward_nonack: no
branch for forwarding
Nov 28 06:11:28 server kamailio[1323]: ERROR:tm:w_t_relay:
t_forward_nonack failed
Nov 28 06:11:28 server kamailio[1317]: Attempting Carrier 1
And here's the watered-down version of my configuration.

Any further suggestions would be appreciated. Thanks!
