asterisk users - Oct 2006 - Can't get second line of Sangoma A200 to work.

I set up extension 120 for the first and 121 for the second.  The first 
one works as expected but I can't get a dial tone on the second one.  I 
hear a buzzing in the second port much like the first, but no dial 
tone.  I have power since the dtmf keys work OK.  I tried changing the  
exten => 121,hint,ZAP/2 to exten => 121,hint,ZAP/1 not really knowing 
what the number after the ZAP/ was, but that didn't work.

Can someone give me a clue as to the proper configuration for the second 
port?  I also can't get the fxo ports to work either but I'll wait to 
ask that one later after I've played with them a bit.  I'm using 
Tribox.  Another strange thing is that when I make a change and press 
the red bar at the top of the page, then Asterisk completely quits 
working until I do a /etc/init.d/asterisk stop and start.  But I can 
live with that.

Thanks,
Jim.
