I called from my office at the University of Houston.  We have some
sort of ancient internal network (most of the switching devices still
don't handle tones, the LD service didn't handle tones until a year or
so ago, etc etc.)  My office number is in my .sig.  The number it gave
me was 713.748.0596.  This number is the number that shows up on a
bill if you call someone collect from on campus, or use some LD
companies (it's been that number for the past five or six years).  If
you dial the number, you get a "not in service" recording from SWBT.

I didn't even have to try to fool it. :-(

[Moderator's Note: Almost the same thing happened when we tried it
today from an extension on a Rolm PBX which has a bunch of DID lines
coming into it. Dialing 9, then the number got us back a message
saying our number was entirely different, but on the same prefix. When
we dialed that number, surprise! The switchboard operator answered,
and said we came up on the number for incoming calls. But the number
read back was not the main number.  PT]
