Thanks all.  As far as why the channel name is in the caller ID, I don't 
know.  I'm certainly not doing it intentionally.  I don't have any code 
in the dialplan that even touches the CallerID, so I guess Asterisk is 
doing somehow when the Name part of the CallerID is unknown...  Either 
that or my Snom 300 phones are picking the wrong info to use for CallerID.
