 Kerry,

 You don't get call progress with FXO zap channels as you would with
VoIP or PRI. That being the case, the FXO port never signals that it
is "ringing" with call progress, but rather, goes to an "up" state
(answered) as soon as it's finished dialing, whether the remote end
has answered or not. You're going to be hard pressed to have a ZAP
channel and SIP channel trying to detect who's going to answer first,
because the Zap/FXO port is always going to win and it's not going to
be because it's always "answered".
