[Users] RE: failure_route.... I could cry...

[Bogdan-Andrei Iancu]

Hi Doug,

correct - you cannot do more than one t_relay at the same time. if you 
to send to more than one destinations, do parallel forking by adding the 
new branches with append_branch("....").

you may also look to t_replicate() (see tm docs) function.

regards,
bogdan

>>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.

>>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.
