[Asterisk-Users] controlling call duration

[Dmitry Mishchenko]

Hello!

Asterisk box receiving calls. Is there some way to get information about 
current calls from external or AGI application?
I'm interested in:
- duration, how long calls already in the system (billing and actual time);
- source/destination phone numbers;
- etc.

In other words can I receive information which we are usually getting in CDRs 
during the time when the call is still active?

Thanks,
Dmitry
