asterisk users - Nov 2005 - Digitmap problems

I'm trying to implement some of the "star services" such as *61
for
weather or *71 for wakeup call, etc. I think I have asterisk setup 
properly because I can get them to work fine using normal extension 
numbers. However, if I try to use the 'star' numbers, my Polycom IP500 
never sends the digits to asterisk, at least I never see Asterisk try to 
do anything in the logs. I believe the phone is giving me a fast busy 
signal because it can not find a match in the digitmap. I've tried 
digitmaps like:

*6x|*7x|2xxx|[2-9]xxxxxxxxx

What am I missing???

The Admin Guide?

I searched through the v1.5 guide, and it implies the digitmap uses
numbers only (no * or #). But, it doesn't actually discuss it either.
