Everything seems to work pretty well with the exeption that the system hangs up on phone calls for no apparent reason.  It does this on both incoming and outgoing calls through the POTS line (currently only have one).  The only thing in the asterisk console with maximum verbousity is " -- Hungup 'Zap/1-1'" and then the phones act like the other side hung up.  The only thing that might be related is that I here beeping or chirping shortly before this happens (it happens randomly thorught calls every couple of minutes but seems to be more prevelent shortly before a disconnect).

Yes.  It's frequently caused by busydetect=yes or callprogress=yes in 
/etc/asterisk/zapata.conf
