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

[x-ser at sidell.org]

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.
