Allowing certain area codes blocking all others
Is there away to only allow certain area codes to ring the phone while blocking all others?
Thanks!

Re: Allowing certain area codes blocking all others
There is no direct way to allow certain area codes, but there is a way to block a large number of area codes with a much smaller number of blocking rules, by specifying numbers that start with one, two, or three digits. For example, to block all numbers outside of the 555 area code, create rules for numbers that start with:
- one digit: 2 3 4 6 7 8 9 (but not 5)
- two digits: 50 51 52 53 54 56 57 58 59 (but not 55)
- three digits: 550 551 552 553 554 556 557 558 559 (but not 555)
- international?: +2 +3 +4 +5 +6 +7 +8 +9
