I’ve spent some nights now trying to get the Busy Lamps on my GXP-2000 working - especially to get them blinking when another phone is ringing. I’ve read several messages that it works fine for some people and studied their configuration examples but I can’t get it working. 
Configuration:
Asterisk 1.2.8 with mISDN
Grandstream BT-101, extension 101
UTstarcom G1000G, extension 103
Grandstream GXP-2000 (firmware 1.1.0.13), extension 1000
(complete config files included below)
If I configure the phones as type=friend it doesn’t work at all.
E.g. if I call extension 101 from extension 103 nothing happens. While extension 101 is ringing “show hints” displays the state as idle.
asteriskCLI> show hints
asteriskCLI>
-= Registered Asterisk Dial Plan Hints =-
1000 : SIP/1000 State:Idle Watchers 1
103 : SIP/mobile State:Idle Watchers 1
101 : SIP/marcus State:Idle Watchers 1
The phones must be configured as type=peer to make it working… halfways…
Now it depends on the call-limit setting. I used to set the call-limit to 1 for the BT-101 and the F1000G. Result:
asterisk*CLI> show hints
-= Registered Asterisk Dial Plan Hints =-
1000 : SIP/1000 State:Idle Watchers 1
103 : SIP/mobile State:Busy Watchers 1
101 : SIP/marcus State:Busy Watchers 1
And with call-limit=2::
asterisk*CLI> show hints
-= Registered Asterisk Dial Plan Hints =-
1000 : SIP/1000 State:Idle Watchers 1
103 : SIP/mobile State:InUse Watchers 1
101 : SIP/marcus State:InUse Watchers 1
In both cases the corresponding LEDs on the GXP-2000 are on. I think this is correct for the state shown by Asterisk - but the question is: Why does Asterisk refuses to indicate a ringing state?
I’ve also set notifyringing=yes for all phones but it doesn’t change anything.
Just to be sure I’ve checked with “sip debug peer 1000” and found no NOTIFY messages from asterisk indicating a ringing state.
The next problem seems to be related to the problem above: If I try to Pickup the ringing line with *8101 or **101 I get error 603. Maybe Asterisk does not accept a pickup because it thinks the phone is not ringing?
For the tests I’ve reduced my configuration files to a minimum:

exten => 103,hint,SIP/mobile

exten => 1000,hint,SIP/1000
exten => 1000,1,Dial(SIP/1000)

Any ideas?
