Sip hints always idle

Hi,
I have 7 aastra sip phone on my asterisk 1.4. And im triying to setup some hints for my sip.
here is what i did :
Extensions.conf:

[blf]
exten => 220,hint,SIP/220

Sip.conf

[220]
username=220
type=friend
dtmfmode=rfc2833
context=torrent-out
video=no
callerid="A. Gingras" <220>
restrictcid=no
secret=1234
mailbox=220@torrent
canreinvite=yes
nat=yes
qualify=yes
host=dynamic
disallow=all
allow=gsm
allow=ulaw
allow=alaw
subscribecontext=blf
pickupgroup=1
callgroup=1

The problem is that if i do a show hints in console i always get :

 -= Registered Asterisk Dial Plan Hints =-
                    220@blf                 : SIP/220               State:Idle            Watchers  1

Even when the phone is ringning or on a line …
Anyone can help ??

there’s been lots of work done on hints recently … check out “limitonpeers” in [general] and “call-limit” and “busy-level” in user definitions … all in sip.conf

you may need to check out 1.4.1 or trunk to get the changes.

Thanks for you answer. Well i just updated to 1.4.1 But do you have more about these option in sip.conf. I search on www.voip-info.conf with no chance. And i also try them but i din’t saw any change in my state

Thanks

Ok ,
Just find out that if you put call-limit=# The states will now change.
