[Asterisk-Dev] Monitoring channel status

[Sergey S. Stasyuk]

Hi all!

I need such thing (subj):
- when somebody dials, I see this (maybe: status - busy|dialing, number 
XXXXXXXX);
- when opponent is answered status changed to smth like "processing";
- when talk is finished, status have to be changed to "free";

I know how to do only the last item.
How to do this doesn't matter - DB, API calls. Preferred way will be to
point me to code, where I can insert my calls (some kind of messages or
signals) if it is not possible to do this with current *.
