[cisco-voip] NANP blocked 900/off shore/telescams route filter

[Joe Cisco]

I plagiarized a route filter several years ago off of a callmanager
that was built by some engineers that worked for a large unnamed
telephone company (I won't say who, but it rhymes with JP&P) Anyway,
it blocks 900 number calls, 976 calls, and a lot of the off-shore and
telescam area codes. I thought I'd share it, and also see if anyone
has any updates or other known area/office codes that companies would
typically want to block.

(AREA-CODE == 242) OR
(AREA-CODE == 246) OR
(AREA-CODE == 264) OR
(AREA-CODE == 268) OR
(AREA-CODE == 284) OR
(AREA-CODE == 345) OR
(AREA-CODE == 441) OR
(AREA-CODE == 473) OR
(AREA-CODE == 649) OR
(AREA-CODE == 664) OR
(AREA-CODE == 758) OR
(AREA-CODE == 767) OR
(AREA-CODE == 784) OR
(AREA-CODE == 809) OR
(AREA-CODE == 868) OR
(AREA-CODE == 869) OR
(AREA-CODE == 876) OR
(AREA-CODE == 900) OR
(OFFICE-CODE == 976) OR
(OFFICE-CODE == 976 AND AREA-CODE EXISTS) OR
(LOCAL-OPERATOR EXISTS) OR
(LONG-DISTANCE-OPERATOR EXISTS) OR
(AREA-CODE == 888 AND OFFICE-CODE == 700 AND SUBSCRIBER == 0400)

Thanks,
