You can get (on the CLI) the list of AMI commands supported by your Asterisk installation issuing "manager show commands".

The AMI command that tells you what a terminal is doing at any time is "ExtensionState" (I guess it's available on 1.4..). But if you add hints to your dialplan, then Asterisk will send an AMI event whenever a terminal in the list of hints is changing state.

You would need to listen to all such events and keep track of each line/extension; issuing a list of ExtensionState events only when you launch your tracking process.
