I'm trying to develop an environment where different SIP clients, located in different networks, register to OpenSIPS. I'm using routers to separate the networks and I'd configure the OpenSIPS in one of these networks.
Before starting the development I'd ask a couple of questions:
- are there any limitations in clustering two OpenSIPS servers (for redundancy) in different networks?
- it can happen that two SIP clients in two separate networks have the same SIP username (normally the telephone number). I think this could be a problem. Should I define some rules to identify the users?
