That's a difficult setup. I've never did this yet and do not know if it
is possible at all. you can use t_replicate but this works only with 1
host. I think someone solved this using forward_tcp.
is it really necessary to replicate 4 times?

Oh dear... it's failing because as far as
t_relay() is concerned, the packet has been delivered, and the transaction is complete,
right? If that's the case, how can I also send the REGISTRATION packet to another
destination? Can I use forward() with failure_route? Arrgh!.

Subject: failure_route.... I could cry...
I am trying to have OpenSER forward registration requests to multiple Asterisk boxes with
failover. Each Asterisk box has two ip addresses. My logic tries to relay to the first IP
on the first Asterisk box (192.168.10.100). If that fails, it tries to relay to the second
IP on the first Asterisk box (192.168.10.17). It then goes on and repeats the process with
another Asterisk box who's IP's are 192.168.10.10.101 and 192.168.10.8.
Actually the first IP address on each Asterisk system is fake (100 and 101)... that's
how I am testing that it will fail to the second one.
The openser.cfg below is causing this to be logged to messages:

Why am I getting the t_newtran and t_relay errors in there? What am I doing wrong? I'm
just calling rewritehostport(next-ip), followed by append_branch() and t_relay. In fact
something really weird happens. When I have the code there for route[20],
failure_route[21] and route[22], it causes the code for the first three routing blocks,
route[10], failure_route[11] and route[12] to act differently. It seems to make route20
fail to connect eventhough it comes AFTER it in the code.
I'd really appreciate some help! Am I doing something wrong with rewritehostport and
append_branch, because quite frankly the docs are terrible.
