asterisk users - Nov 2004 - DID/PRI sending to the s, extension instead of t he DID extension

I've got some DID's on a PRI that I want to ring an extension when the
trailing digits match an extension in the dialplan. 

Followed the instructions at:
http://www.voip-info.org/wiki-Asterisk+tips+DID

When I call the DID, Asterisk is not recognizing it as a DID and instead
sending it to the "s," extension in the same context. 

My PRI debug:

The target context:

exten => 0545,1,answer <--this doesn't kick in
exten => s,2,blah <---this is processed instead

Digium T100P <-----> Adtran Atlas 550

Atlas 550 is configured with User termination to the * box and Network
termination to the PSTN. On the User term, Strip MSD is off, Called Digits
Transferred is manually set to Four

Outbound calls work fine.

put an underscore and see if it helps:

exten => _0545,1,answer

Thanks for replying.

Good idea, but no effect.
