Please allow IP range in X_Access List to stop SIP Scanners

Obi? Will you respond?  This will be a security enhancement for Obi users, and will elimate a great deal of annoyance.  Thank you.

There is a similar topic here:

I guess there is a difference between wanting to block certain IP's and wanting to block ALL of them, but essentially I think everyone from both threads wants the same thing.  It would be much easier to just have an option like the Grandstreams to reject anything not coming from the SIP proxy configured.  So I guess it would have to do a reverse DNS lookup for each incoming call and then handle it accordingly.

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.

Ok, X_AccessList 67.222.131.147 (sipsorcery.com) is from where I receive my inbound calls.

Problem solved ?

Problem solved maybe for you. Larger providers use many servers so this approach is not feasible. Callcentric has a couple of hundred:

204.11.192.0/24 (as in 204.11.192.0 - 204.11.192.255)
66.193.176.0/24 (as in 66.193.176.0 - 66.193.176.255)
