asterisk users - Oct 2008 - Tracking T1/PRI channel status - inbound vs. outbound

I need to monitor the states of my T1/PRI Zap channels.  Specifically, I 
need to be able to programmatically determine whether a channel is 
unused, carrying an inbound call, or carrying an outbound call.

Using the manager interface, I can easily tell whether a Zap channel is 
used or not by looking at the results of:

   Action: Command
   Command: zap show channel <x>

Or:

   Action: Status

However, nothing in those results seems to reliably indicate whether the 
channel received an incoming call or was used to make an outgoing call.

I can make educated guesses based on the value of "Caller ID" or 
"Calling TON" or the combination of "Channel" and
"Link", but none of
these heuristics seem robust.

I've even tried GetVar-ing various channel functions, to no avail.

This seems like a case where a simple flag should be set somewhere, but 
I haven't found one.  What's the most elegant way to do this?  Thanks.

It gets all data from AMI and runs as a daemon that populates a DB.

It's beta, site claims 5 calls for free but I am not sure for beta software,
I would not pay for Beta software, never used it but it is new.  .09Beta

Interesting anyways, seems the concept/code would be easy to reproduce if
pricing is an issue.
