Blocking long distance directory assistance

[ClydeP]

Looking for a method to block calls to North America long distance directory assistance (area code) 555-1212. This requires the ability to block the specific local exchange and number along with all area codes in NA (+1). I attempted a wildcard "1-9,1-9,1-9,5551212" with length of 10; system shortened to "1-9,5551212"; moved to top of list of Outbound rules, and it worked, but it also blocked all 10 digit calls.

Any suggestions? Or is this a function that I need to see if available from SIP provider?

Since you can't use wildcards in outbound rules (at this point), you'd have to create a rule to deal with every areacode, or, talk to your provider, and hopefully they can block those (premium) calls.
