This isn't really an application question, but StackExchange doesn't really have a VoIP/Phone forum from what I can see.
Anyways, I have an Asterisk server setup at our office and its just on a normal POTS line. Tonight I saw a call come in from caller ID 1702347605. I couldn't get to it in time and I wouldn't have answered it anyways. Of course, that number is either not valid or I'm not seeing the sequence right. Since the caller ID doesn't show the leading 1, here are some possibilities for what it could be:
17-0234-7605 - Looks like a country code? But I can't find 17 as a country code.
170-234-7605 - Of course area codes below 200 aren't allowed in the NA numbering plan
1702-347-605 - Some new Caribbean area code? I can't find any evidence of this though.
Was the caller ID just faked? I know this is possible and that there are some phone companies out there that allow this. I've looked around online and other people seem to also be confused about this number and ones like it.
I know I could just let it go, but enough people seem to be asking that question online that it really deserves a better answer. Hopefully someone here will know.
