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.
