[OpenSIPS-Users] Multi-Proxy Environment Routing

[Duane Larson]

Correct.  I meant Priority.  I set my Primary Server as "0" and backup as
"1".  For the db_mode I use 3 which is "DB Only" mode.

I did look into the possibility of using Bin replication but it sounds like
in order to use that both OpenSIPS instances have to use the same IP
address.  Will see what I can do with t_relay'ing INVITE's to the correct
Proxy that the client is registered with.

Thanks
