asterisk users - Jul 2005 - Call Status from a IAX trunk to a Zaptel trunk

Hello,

I'm actually sending calls from a * box1 to * box2 for termination through a
zaptel channel using an IAX2 channel.
My problem is that * box1 is always getting an "ANSWER" on the call
even if *
box2  cannot successfully terminate the call. The Zaptel channel on * box2 is
always "ANSWERING" before sending the call on its zaptel channel.

How can i setup one of the 2 boxes to get DIALSTATUS to "ANSWER" only
if the
call is correctly terminated by * box2 ?

Thanks for your help.

Moussgrd.
