[asterisk-users] Retrieve Call setup - QoS

[Carlo Dimaggio]

Hi all,

I would like to know if there is a function/setting for extracting the  
call setup time in asterisk (1.4 or 1.6).
I need this value for every call processed by asterisk as specified in  
(ETSI TR 101 329-1 v3.1.2):
Call set-up time is the time elapsed from the end of the user  
interface command by the caller (keypad dialling, E-mail alias typing,  
etc.) to the receipt by the caller of a meaningful progress information

In other words:
	Call setup time = time from call start (caller press the # key -  
start the invite) to session progress (183) or ringing (180)


Thanks and best regards,
Carlo Dimaggio
