[Serusers] best way to allow outbound calls from multiple SEMS serves

Greetings.

In my application, there will be multiple SEMS servers making outbound (PSTN) calls via a common SER proxy.

In ser-oob.cfg, the following code allows a single gateway to send invites without authentication:

# Gateways are usually not able to authenticate for their requests. # You have to trust them base on some other information such as the # source IP address. # WARNING: If at all this is only safe in a local network! if (@src.ip == $gw_ip) { break; }

I suppose I could perform the test multiple times, once for each SEMS server. But, I wonder if there is a nice 2.0-style database-oriented way to allow invites from multiple trusted sources?

Thanks again.
