asterisk users - Jan 2009 - goto iax problem

Dear,
the goto function to the iax dialing, makes  bill duration and call duration
wrong, in cdr.they are equal to ringing time.
the cdr will be produced and saved into the dbase, when the callee picks up the
phone.

is any way to have real duration time ?



[main]
exten => _1X.,1,GOTO(LOPL,${EXTEN},1)
....


[LOPL]
exten => _X.,1,Dial(IAX2/MAIN/${EXTEN},60)
