I should have mentioned before that the scenario I mentioned was with
IAX2 trunking. I don't use SIP for inter-switch trunking but I do for
terminating lines. Maybe IAX2 and SIP handle Caller ID differently.

Sorry, by this you mean that Asterisk does not see the number or that
the telephone set does see it? It sounded like the former.
One thing to note is that prohib and unavailable function differently.
I looked at my code, and if a subscriber does not subscriber to Caller
ID, I do something like the following:
unavailable and prohib options are interpreted differently by different
SIP clients (e.g. ATAs or softphones). I did some testing and found that
there was inconsistent behavior with one option vs. the other.

It may not be Asterisk but the telephone itself. I tested with a soft
phone and it shows Anonymous <anonymous>. However, an actual telephone
set shows "PRIVATE", regardless of which option I choose. But, this is
just a hunch, and I'm not certain.
