:: groundstart and loopstart :: Update<BR><BR></DIV></FONT>
<DIV><FONT size=2>Thanks for the responses.</FONT></DIV>
<DIV><FONT size=2></FONT> </DIV>
<DIV><FONT size=2>Here is an update on my zap groundstart, loopstart,
"disconnect supervision" woes. Apparently, the
groundstart mode in the CAC FXO module works on loopstart lines. I
still don't understand how and why.</FONT></DIV>
<DIV><FONT size=2></FONT> </DIV>
<DIV><FONT size=2>I have loopstart lines.</FONT></DIV>
<DIV><FONT size=2></FONT> </DIV>
<DIV><FONT size=2>The only way "disconnect supervision" works on
my system is if I set the FXO module to groundstart. However!
There is a big caveat. In groundstart mode, incoming caller ID stops
working! This is something I am going to have to live with for now as
disconnecting the line on hang-up is far more important than caller
ID.</FONT></DIV>
<DIV><FONT size=2></FONT> </DIV>
<DIV><FONT size=2>I have no idea if the caller ID problem is a problem
with CAC FXO modules or the zap channel software or the fact that we are
using groundstart signaling on a loopstart line.</FONT></DIV>
<DIV><FONT size=2></FONT> </DIV>
<DIV><FONT size=2>I can confirm that this is the behavior with both CAC I
and CAC II units as I have a CAC II unit and I spoke with Michael on this
list who has a CAC I unit. Both of us are in the same
predicament.</FONT></DIV>
<DIV><FONT size=2></FONT> </DIV>
<DIV><FONT size=2>Anyway, I hope others find this info useful. If
anyone has any other ideas on how I can get my caller ID to work I would be
really excited about that.</FONT></DIV>

<DIV><FONT size=2>Thanks,</FONT></DIV>

<DIV><FONT size=2></FONT> </DIV>
<DIV><FONT size=2>PS: I have seen people mention that, when you have many
lines, PRI is cheaper. This is not our case at all. San
Francisco. We have eight lines at the cost of $0.01 per line.
All we pay for really is the call time.</FONT></DIV>

<DIV><BR></DIV>
<DIV><FONT size=2>Hello Astrites,</FONT></DIV>
<DIV><FONT size=2></FONT> </DIV>
<DIV><FONT size=2>I was just about to send out a long email about not
being able to detect hang-up with my CAC II FXO module on my PSTN POTS
lines. I had tried many configurations. I had attached a
toner to the line to see if I was getting this "disconnect
supervision" signal after hang-up. (toner has a line powered
light in the off position) It seemed that I was getting the
signal, as:</FONT></DIV>
<DIV><FONT size=2></FONT> </DIV>
<DIV><FONT size=2> The light was steady on
onhook</FONT></DIV>
<DIV><FONT size=2> When the line rang the light
dimmed.</FONT></DIV>
<DIV><FONT size=2> When I picked up the line stayed
dim (If I remember correctly)</FONT></DIV>
<DIV><FONT size=2> When the other end hung up the
light stayed on</FONT></DIV>
<DIV><FONT size=2> Then turned off momentarily a few
seconds later. (I suspected this was "disconnect
supervision")</FONT></DIV>
<DIV><FONT size=2></FONT> </DIV>
<DIV><FONT size=2>Anyway asterisk never detected hang-up.
Everything else worked. I was frustrated as hell.</FONT></DIV>
<DIV><FONT size=2></FONT> </DIV>
<DIV><FONT size=2>After a few days of trying everything, I tried to set
my CAC II FXO module to Groundstart and configured zaptel.conf and
zapata.conf to groundstart signaling.</FONT></DIV>
<DIV><FONT size=2></FONT> </DIV>
<DIV><FONT size=2>Voila! Everything work!</FONT></DIV>
<DIV><FONT size=2></FONT> </DIV>
<DIV><FONT size=2>The question is how does groundstart and loopstart
work? How was I able to have a somewhat working system using
loopstart when it seems that the phone company signaling was
groundstart? Can I assume that my lines are indeed
groundstart?</FONT></DIV>
<DIV><FONT size=2></FONT> </DIV>
<DIV><FONT size=2>I am really happy that it works. I can now begin
the process of deployment with a much greater feeling of
security.</FONT></DIV>
