asterisk users - Jun 2005 - Call Manager & Asterisk for VM - MWI not working

Like some other people on here, I am trying to integrate Asterisk for VM 
with CCM version 3.x.  I've got gnugk and Asterisk running, I've got CCM
registering with the GK, I've got the voicemail pilot and profiles 
setup.  A call comes into a CCM phone, it rings, rolls to the correct VM 
on ASterisk and asterisk emails the voicemail and I can check the 
voicemail, but I cannot get MWI to work at all.  I'm using Shaun's 
script below:

root@Claven /etc/asterisk# more vm.sh
if [ $3 -gt 0 ]; then
# TURN LITE ON
CALLFILE=$(cat <<-EOF1
Channel: Local/11$2
MaxRetries: 1
# Retry in 2 min
RetryTime: 120
WaitTime: 45
Context: default
Extension: s
Priority: 1
EOF1)
echo "$CALLFILE" >>
"/var/spool/asterisk/outgoing"/$(date +%Y%mNaVI%M%S)-$1

else
# TURN LITE OFF
CALLFILE=$(cat <<-EOF1
Channel: Local/00$2
MaxRetries: 1
# Retry in 2 min
RetryTime: 120
WaitTime: 45
Context: default
Extension: s
Priority: 1
EOF1)
echo "$CALLFILE" >>
"/var/spool/asterisk/outgoing"/$(date +%Y%mNaVI%M%S)-$1
fi


I changed it to 11EXT and 00EXT because it made more sense to use 11 to 
turn on MWI and 00 to turn it off.  Within extensions.conf, I have:

exten => _00XXXX,1,SetCallerID(${EXTEN:2})
exten => _00XXXX,2,Dial(H323/8999@10.50.1.10)
exten => _00XXXX,3,Answer
exten => _00XXXX,4,Wait,1
exten => _00XXXX,5,Hangup

exten => _11XXXX,1,SetCallerID(${EXTEN:2})
exten => _11XXXX,2,Dial(H323/8998@10.50.1.10)
exten => _11XXXX,3,Answer
exten => _11XXXX,4,Wait,1
exten => _11XXXX,5,Hangup

8998 and 8999 are the MWI on and off #'s.  10.50.1.10 is the Gatekeeper. 
  I'm kind of at a loss of what to try next.  Here is what I get with a 
h.323 debug and the * logs:

I am calling 7757.  The call works, it plays vm, I record the message 
and then hang up and I get the info above.  I see extension s in the 
script and it's referenced above, but I am not sure how extension s 
should be setup, or if it's even necessary.  I understand the theory of 
the script, but not the details of what exactly it is trying to do, so 
maybe that's my issue.  Note that Asterisk is NOT sending anything out 
"on the wire".  Packet captures show that it is not even trying to
send
out a call to lite the MWI.

Any thoughts or pointers?  Thanks.
