I am familiar with the Incoming Signal Validation outlined in UC 4.0.1 and above's Admin Guide as outlined on Table 9-2; Incoming Signal Validation
I'm looking to see if there is a way to have Polycom UC phones will only answer calls intended for an AOR which is currently registered on the Polycom UC phone.
Example, I have a Polycom phone registered to Foo@126.96.36.199 on the public internet. Someone SIP scans the IP address and finds the phone and begins to send random calls to that phone such as email@example.com, firstname.lastname@example.org.
Is it possible to only allow the phone to ring for calls addressed to Foo@188.8.131.52?
