asterisk users - May 2010 - identify caller hangup or callee hangup?

Hello,

you know , when a call setup, either caller hangup first or callee
hangup first , the hangupcause will set to 16(means Call Clearing
Causes)

My question is how could i identify whether the caller or callee
hangup the phone first?

Best Regards!

AFAIK you can not.

The only way I can think of doing it is that if one end involves the use 
of ISDN then in the console logs you do get messages like
"-- Channel 0/11, span 1 got hangup request, cause 16"
but there is no timestamp so it would be tricky matching up to the 
corresponding call

Maybe you can try using the manager interface. The hangup event seems to 
mention the channel so perhaps this is the one which initiated the hangup

I think You can do this if you use local channel.
For example, you do two context
AEL example

context	Incoming {
	_X. => {
		......
		Dial(Local/${EXTEN}@Outgoing/n);
	};
	h => {
		Noop(Hangup in Incoming);
	}
};

context Outgoing {
	_X. => {
		..........
		Dial(SIP/dd at dd);
	};
	h => {
		Noop(Hangup in Outgoing);
	};
};

I think this is must work. I have like so, but use with callout files.

Have you looked at Dial's g option ?
"*g*: When the called party hangs up, exit to execute more commands in the
current context."
