End to End VoIP delay calculation

[capricorn 80 <cool_capricorn80 () hotmail com>]

 Hi!
 I am looking to calculate the end-to-end delay between two soft phone/hard phone. I have asterisk server and 
configured ntp server on the same machine and synchronized it with ntp pool.  I have seen that Wireshark can be used to 
check the jitter. But I am not sure how can i calculate the end to end. 
May be this is not related to the mailing list topic but please help me if anyone has some information.
Regards,
