But if you use db_mode, the 2 proxies do share all the registrations via
the DB (you mentioned they do use the same DB). So even if a
registration in stored by P1, P2 will also see it. So both proxies will
see exactly the same set of registration, disregarding which proxy
actually did store for a certain registration.

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.

Hi Duane,
First, in regards to your DNS records - I suppose you use higher
priority and not higher weight ? The weight are used to control
how many (as ratio) times each record is used. If you want to have
all the time R1 and have R2 only if R1 is done, then you should
use priorities.
Now, you mentioned both proxies do use the same location table in
DB. But what db_mode is used in the usrloc module ? If you have
DB_ONLY mode, I see no problem with the scenario you described (as
both proxies will read/write from/to single DB). If you use other
db modes, you will probably need to use the bin replication in
usrloc module in order to sync the cache too.

Before I try to reinvent the wheel I wanted to see if there is
already a way to do this.
For redundancy I have two Proxies and I am using DNS SRV with
Proxy01 weighted higher so that it is the primary that all
clients register and use. Both proxies use the same location
database. In the event of a failure on Proxy01 all clients would
register with Proxy02. Everything is fine but what happens when
clients register time expires and they start re-registering with
Proxy01 since it is weighted higher. So now some clients will be
registered with Proxy01 and some with Proxy02. Everything will
work fine but what if Client01 (who is registered with Proxy01)
calls Client02 (who is registered with Proxy02)? I think the
INVITE should do the following
Client01 -> Proxy01 -> Proxy02 -> Client02
On Proxy01 I could look in the location database to see what is
set in the "socket" field and then route it to Proxy02 but I was
wondering if there is already a way to do this?
