Ive Block 1900 and 976 but what else should I block?
I have block 1900 and 1976 from my callmanager to prevent abuse, are there other codes that I should block. What about 809? How about the 20 other splits of 809? I just got some spam about 809 area codes being used to scam people like 1900 numbers. But Im not 100% sure I should block 809.
Basically, it says that everything regarding the 809 is basically true. With that in mind, as with any good access list, block it. Once all the changes have been made (and as a good practice) I would let your users know what you have blocked, that way if they have a legitimate 809 (there are some) number then you can fix it for them as opposed to them getting frustrated at the phone system.
