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.
