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@1.1.1.1 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 1001@1.1.1.1, 1002@1.1.1.1. 

 

Is it possible to only allow the phone to ring for calls addressed to Foo@1.1.1.1?

 

thank you!
