[Asterisk-Users] How detect connection setup/teardown with manager interface?

[Maciek Kaminski]

May problem is: I need to know when and between which channels 
connection is setup and hungup. Is there a way to learn this from 
manager interface? There are Link/Unlink events but then appear more 
than once during single connection, ie while calling from IAX to SIP I get:
Event: Link
Channel1: IAX[kamyk at 192.168.0.3:5036]/3
Channel2: SIP/kamyk-9950
Event: Unlink
Channel1: IAX[kamyk at 192.168.0.3:5036]/3
Channel2: SIP/kamyk-9950
Event: Link
Channel1: IAX[kamyk at 192.168.0.3:5036]/3
Channel2: SIP/kamyk-9950
before connection actually is made.

Any help?
