Thank you very much for the pointer. I wanted to acknowledge how valuable it was. I was able to monitor the channel. I did not know that tool exsited or what it did. Now I do.
I actually do not know what an FSK tone is. I gather, from google, that it is some audible tone between the first and send ring. I was not able to to hear anything between the rings. However, my caller ID stopped working in loopstart mode as well. So... I have to dig deeper.
Thanks again,
Jason

Thanks for the responses.

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.
�
I have loopstart lines.
�
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.
�
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.
�
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.
�
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.

Thanks,
Jason

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.

Subject: [Asterisk-Users] Question :: groundstart and loopstart
Hello Astrites,
�
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:
�
��� The light was steady on onhook
��� When the line rang the light dimmed.
��� When I picked up the line stayed dim (If I remember correctly)
��� When the other end hung up the light stayed on
��� Then turned off momentarily a few seconds later.� (I suspected this was "disconnect supervision")
�
Anyway asterisk never detected hang-up.� Everything else worked.� I was frustrated as hell.
�
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.
�
Voila!� Everything work!
�
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?
�
I am really happy that it works.� I can now begin the process of deployment with a much greater feeling of security.
