Hi Doug,

if you have:

rewritehostport("192.168.10.7:5060");
t_on_failure("2");
t_relay();

failure_route[2] {
	rewritehostport("192.168.10.7:5060");
	append_branch();
	t_relay();
}

you do serial forking - try first destination and if fails, o for the 
second one.

for:

rewritehostport("192.168.10.7:5060");
append_branch("192.168.10.7:5060");
t_relay()

you do parallel forking - the request will be sent in the same time to 
all destinations.

regards,
bogdan

They all use append_branch("sip:user at domain") which in the real world is barely useful. I need to try sending messages to a specified host with the current user's URI.
