[VoiceOps] Curious Caller ID issues

[Darren Schreiber]

Thanks Markus & John for the replies. The mystery remains but that thread you sent John from 3 years ago appears to be similar re: symptoms.

We'll keep hunting this down with our carrier.

    It would be interesting to know which service the callers are making 
    their calls through.
    
    Is it from their US cell phone directly via their cell provider?
    
    Is it from a landline in the US?
    
    Because, if it is some kind of VoIP service or if these calls originate 
    from people living abroad or if they are currently roaming, it could be 
    that the CLI is simply forged by the originating carrier or somewhere 
    along the path and was set to some spontaneously made up value (789-0000 
    = 7 8 9 0 <- may be legit but since the digits are consecutive... it is 
    something that I would type if I had to make up a number quickly).
    
    If it really from their cell phone or landline then I would also go with 
    the misconfiguration theory.
