Bogdan...

Thanks for the info. Ok... well I think I need to do serial forking. I don't want to
have a situation where the registration  gets delivered to two IP's on the same host
because both happen to be available. I don't think Asterisk will have a problem with
it, but to be safe I'd like to avoid that. So, back to my original logic of trying
first ip on first Asterisk box, if that fails try second ip on first Asterisk box. Then,
move onto the next and repeat the process.

With pareallel forking, what happens with failures? Does a failure of any single host in
destination set cause an error that can be handled with failure_route? Or, do all hosts
have to fail before you can detect an error? How can you determine which one failed?

I don't think parallel forking is what I need, but thanks for clearing that up for
me.

Doug.

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

 I'm having a terrible time trying to get failure
routes to work. Can someone point me to some USEFUL examples please? The examples that
come with OpenSER are trivial. They all use append_branch("sip:user@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.

For example, is this the correct usage for trying to connect in sequence to multple
destinations?

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

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

The second route is never tried. In general, what should I be doing here? 
Which is correct?

rewritehostport(ip-addr)
append_branch()
t_relay()

or maybe...
append_branch(ip-addr)
t_relay()

or maybe...
append_branch(ip-addr1)
append_branch(ip-addr2)
t_relay()

Do you get my point? The docs are really bad and don't cover exactly how this stuff is
supposed to be implemented! if I do a google search on this stuff, I get almost no
matches. There's no books either. I'm out of ideas.

I'm just trying to connect to multiple destinations in sequence....
