asterisk users - Sep 2005 - Two POTS in, but only want one out?

Hi!  I've got two POTS lines coming in to my * box, but I only want the
primary of the two lines available for outbound dialing.  I can't quite
figure out how to make that happen.  Suggestions?

Thanks,

How about something like this?

 exten => _9XXXXXXX,1,Dial(Zap/2/${EXTEN})

which dials out on the second zap channel/port.
