[Freeswitch-users] fs_cli | show calls | answer timestamp

[Dmitry Mordovin]

Hello All!

I use fs_cli api for interraction with FS from my application.

Now I wish get current active calls (api show calls) and calculate 
current duration.

"show calls" output many fields, but timestamp represent call originate 
time and no one field with timestamp
represent b_leg answer time (SIP 200 OK message)

So, any idea (easy implementation) to obtain SIP 200 OK timestamp or 
current call duration since 200 OK received?
