[asterisk-users] Newbie Polycom: Subscription/Presence Problem

[Lee, John (Sydney)]

I am working on Polycom IP601 console with expansion module.
I want to put on the BLF (busy lamp field) feature on all the
contact/speed dial names I put on the console but I could not get it to
work.

*CLI> core show version
Asterisk 1.4.13 built by root @ hostname on a i686 running Linux on
2007-11-20 05:26:15 UTC

*CLI> sip show subscriptions
Peer             User        Call ID      Extension        Last state
Type            Mailbox
172.19.20.15    8000        8b1a76cc-68  8166 at default     Idle
xpidf+xml       <none>

*CLI> core show hints
    -= Registered Asterisk Dial Plan Hints =-
                   8166 at default             : SIP/8166
State:Idle            Watchers  1
----------------
- 1 hints registered

I thought I did all the right thing but for some reasons the last state
is always Idle even though I press the DND (do not disturb) button or
change the state via the MyStat soft key, not to mention that the light
next to the speed dial never lighted up.

Here is what I did:
***sip.conf

[general]
subscribecontext = default      <=====
notifyringing = yes             <=====
notifyhold = yes                <=====
limitonpeers = yes              <=====

[8166]
type=friend                     
context=default                 
host=dynamic                    
dtmfmode=rfc2833                
username=8166                   
secret=polycom
qualify=yes
mailbox=8000 at default
call-limit=99                   <=====

***extensions.conf 

exten => 8166,hint,SIP/8166

***sip.cfg on the boot server
   <feature feature.1.name="presence"
            feature.1.enabled="1" ...  <====

***<mac address>-directory.xml
                        <ln>Blah</ln>
                        <fn>Blah</fn>
                        <ct>8166</ct>
                        <sd>1</sd>
                        ...
                        <bw>1</bw>   <====
                        <bb>0</bb>

Any thoughts?
