[OpenSIPS-Users] Multi-Proxy Environment Routing

[Bogdan-Andrei Iancu]

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.
