Ghost Calls Round 2

We were getting many complaints from our users that they were getting "ghost calls" from random numbers like 101, 1001, etc. The phone would ring incessantly and when they picked it up it would just be dead air. We discovered this was a symptom of port scanning by scammers. The setting in the newer firmware "Allow IP Calls" when disabled stopped this from happening. However, the issue has cropped up again on phones where this setting is set to disabled. Any ideas?
