Wow... talk about a detailed response; thanks!

In our situation, we've got a T-1 voice PRI from Allegiance Telcom. For 
the benefit of those of us who aren't as in the know as you are (and 
who have no affiliation with a CLEC), is there a way to be able to 
control what gets sent out as our name portion of the Caller ID (even 
if it means changing what's recorded at Allegiance)? We somehow manage 
to do so with the number part.

In other words, type real slow and mention specific conf files if 
possible. This is pretty new stuff for me...  Thanks again!
