[Asterisk-Users] Snom 220 busy lamps [was: Receptionist phone...]

[Tracy R Reed]

I am so far unable to get the busy lamps on a Snom 220 to work either with
current cvs or asterisk 1.0.

I am using the hint extension and the Snom 220 just as described in the
"mini-howto" on:

http://www.mail-archive.com/asterisk-users@lists.digium.com/msg49781.html

There are also a couple of wiki pages referencing this:

http://www.voip-info.org/wiki-Asterisk+standard+extensions

This one seems a bit out of date:
http://www.voip-info.org/wiki-Asterisk+phone+SNOM

I have created hint priorities in my dialplan:

exten => l00,hint,SIP/100
exten => 100,1,Macro(stdexten,100,SIP/100)

I have this set up for phones 100-110. Phone 110 is the receptionists
phone and 100 is a normal users phone. I also have
subscribecontext=default in all of my sip.conf entries which the
mini-howto above completely neglects to mention. Is it necessary? I have
gone to the configuration page on the phone and set the function keys to
be type "Destination" and put in the numbers of extensions 100-110 which
the phone then converts to a sip uri. The sip uri has user= at the end.
It defaults to 'phone'. Does this matter?

If I do a sip debug peer <peername> on the receptionists phone I can see
it successfully subscribe to all of the appropriate channels. If I do a
sip show subscriptions it shows me:

*CLI> sip show subscriptions

0 active SIP subscriptions(s)

What does the "User" column represent? It is odd that all of them say 110
(the receptionists phone) except for one which says 100. Extension 100 is
a Snom 200 but all of the rest of the phones are Cisco 7960's. But the
lights do not work regardless of whether I make a call with a Cisco or the
Snom phone. What should be in the URI column? Does the fact that it is
empty mean anything?

One odd thing is that if a phone is actually online and reporting a
status the light on the keypad is illuminated. This seems opposite from
what I would expect. I would expect the light to come on only if the phone
is busy. If the phone is offline for some reason the light is dark. But
the status of the light never changes even when I am making calls on one
of the phones.
