asterisk users - Jul 2005 - Cisco Call Manager with Voicemail on Asterisk Problem

I've followed the wiki and can't get the message waiting indicator to
light
on the phones connected to the CME.

The * console gets messages that registration failed - 
Jul 20 13:27:33 NOTICE[22017]: chan_sip.c:7708 handle_request: Registration
from '<sip:6502$@172.28.1.34>' failed for '172.28.0.100'

I get one message for each number that is setup on the CME box.

Any ideas on what I might be missing?

Rick
