too many server addresses to list making it impractical or impossible to setup in the OBi.

And that's exactly why the access list feature is an unacceptable solution to this problem.  There needs to be a feature that specifically rejects traffic not coming from the SIP proxy.

OBiSupport:
Please see the OBi Admin Guide (p. 94) for details on the parameter called ”X_AccessList”.

X_AccessList
A comma separated list of IP addresses such that the device only accepts SIP requests coming from one of the given addresses. If the list is empty, the device accepts SIP requests from any IP address

This is found in the ITSP SIP Settings area of the configuration.

Not trying to be rude, but did you read the messages in this thread?

Is that not what Obi Support is saying?  "A comma separated list of IP addresses such that the device only accepts SIP requests coming from one of the given addresses."

Right. He's suggesting X_AccessList. Unfortunately (as mentioned in this thread) this will not work for a large number of servers (something Callcentric has)
