[asterisk-users] How to check a number online or offline

[Jim Dickenson]

If you do an AMI packet like this:

Action: Originate
Channel: Local/get_info at some_context
Exten: do_noop
Context: some_context
Priority: 1
ActionID: GetInfo
Async: true

and then have a couple extensions that do what you want. Here is what I do in my case:

exten => get_info,1,Answer()
exten => get_info,n,UserEvent(GetInfo,Version:ABE & DateTime:${STRFTIME(${EPOCH},,%Y%m%d%H%M%S)} & CfMC:83351)
exten => get_info,n,Hangup()

exten => do_noop,1,Answer()
exten => do_noop,n,Wait(1)
exten => do_noop,n,Hangup()

You would then do what you need to do in your extensions.

Your suggest uses function DEVICE_STATE but this is written in dialplan not application java. Do you know other way to do this for me?thanks and looks forward to listening your reply.
