asterisk users - Jul 2007 - TDM04B & FIOS No Hangups Often

Hello all, I am having a big issue that i just cant get fixed for a
while now and its causing me lots of grief.  It seems like since we got
FIOS installed (including switching to fios phone lines which are
supposed to be the same on our end) i am having massive problems with
asterisk not hanging up dead calls for days, even weeks if i dont catch
it.  It slowly builds up randomly not ending a call and then next thing
i know all our lines are busy and they all say a call is active in show
channels.  i have to shutdown asterisk and then restart and then it goes
back to normal.   
 
not every call does this either, its just random.  I believe it started
when the fios was installed but its possible it didn't, i thought one
time a iax2 channel was like this but i havent been able to repeat it.
I am unable to repeat this on demand, its just random.  Do I need to add
something to zapata.conf for fios pots line? 
 
For those that dont know, FIOS is verizon's new fiber optic service,
running fiber to your house and then converting it to copper lines and
computer internet via a demuxer of some sort.
 
Please help, this is driving me nuts.  I am using snom 360 phones,
1.2.21.1, 1.2.18 zaptel.
 
Thanks
 
Mike

Some things to try:
1) Set the FIOS/zaptel lines to kewlstart signalling (if you haven't
already done that).
2) Set callprogress=yes in zapata.conf (if you haven't already done that).
3) Do you have explicitly declared hangup() statements in your
dialplan?  If not, you could try adding a few in key places as a test.
4) Verify with Verizon that you have disconnect supervision on your
lines.  I would think that they should be able to provide disconnect
supervision on these high tech lines, but maybe the demuxer you
mentioned screws this up.
