Neighborhood Spoofing Filter (Term RP)
This feature allows you to block Neighbor spoofed calls. Neighborhood spoofing is when you get a call from an unknown number that looks a lot like the numbers where you live. The incoming call will have the same area code and maybe the same prefix (the three numbers after the area code) as your number. Malicious actors do this hoping you'll think it's a neighbor and answer the call.
This can be found within a Termination Routeplan:
Digit Match: is number of digits that will be used to determine neighbor number. 3 digit means it will match on NPA level, 6 digit means it will be NPANXX level.
Action: Currently the only option is to Block Traffic.
SIP Code: When the action is performed, the defined SIP code is returned.
SIP Reason: When the action is performed, the defined SIP reason is returned.
