[Asterisk-Users] sip channel status - how?

[Peter Hoppe]

Hello!

I have an asterisk setup where several sip devices are connected to an 
asterisk box. I am looking for a method that lets me know whether any of 
the sip devices is on hook / off hook / busy etc.

I have tried the AGI command CHANNEL STATUS <channel name> but it 
returns with a message

'There is no channel that matches <channel name>'

In concrete terms, my channel is a Grandstream BT 100, and I have 
configured it as user 'test-1'. But when I query its state I get

'There is no channel that matches test-1'

When I use test-1 my log shows a device 'test-1-<4-digit-hex-code>', and 
I suppose that I need the 4-digit-hex code to enable asterisk to find 
the matching channel with the AGI CHANNEL STATUS command. Unfortunately 
that number seems to be assigned to a different value whenever the 
'test-1' device is used.

Is there any agi (or other fast-agi/eagi/manager/dialplan) command or 
technique through which I can find the state of my channel 'test-1' 
without me having to specify the 4-digit-hex-code?

Thank you very much!

Peter
