[asterisk-users] Determine When Call Is Picked Up In Queue

[Joseph Begumisa]

Hi,

I have a situation where a call comes in to my asterisk server, goes
through an IVR and is then handed off to another asterisk server where
it enters a queue waiting for an agent to answer the call.  (I do not
control the second asterisk server).

Is there a way for me to know when the call is actually picked up on
the second asterisk server?  I have a billing application that needs
to start billing when the call is actually answered by an agent.

Thanks a lot.

Best Regards,

Joseph
