[VoiceOps] Strange inbound Calls

[Nick Olsen]

If the call is answered by a human, They hear nothing on the other side. I 
will ask our receptionist to allow the call to continue for a minute or so 
and see if it hangs up at the 60 second mark.
Timing our own IVR. It takes exactly 60 seconds, If you press nothing to 
get all the way 1 second in to voicemail. As these calls always appear 
leaving 1 second voicemails.

Are the calls answered by a human?  If so, what do they hear?  If not
and it's an IVR, if you call and say nothing does the call drop in 60
seconds?

City and state are not uncommon for CNAM.  Many CNAM providers will put
the city and state of the rate center for the NPA-NXX if caller name
isn't available.
