asterisk users - Jun 2005 - Newbie Confusion on Call Forward and DBput/DBdel

I have the standard script for activating call forward and when I do a 
database show, I indeed see:

/CFIM/2000         :12125553434

so I presume that means call forwarding is in effect.  However, when 
anyone dials extension 2000, it rings and no forwarding takes place.

Is there something basic I'm missing here?  Does one have to define, 
first, what CFIM is?

The Newbie Thanks!

I forgot to mention in my previous post that as well as:

/CFIM/2000         :12125553434

showing up in the database, the phone is registered properly and also showing up
in the database show.  For some reason it
seems that Asterisk is not reading the database before connecting the call. 
Does that sound right?

Using CVS-HEAD

Thanks,
