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
