From what I was able to figure out from my the logs, asterisk will not do busytone hangup detection when using Kewlstart. I guess Kewlstart expects a battery drop to indicate hangup so I tried Groundstart (which failed to load) and Loopstart. Now when I use Loopstart asterisk doesn't seem to detect the hangup using the battery drop but it does eventually detect it. My guess is that it only uses busydetect with Loopstart signalling. With fxs_ls and the busydetect=yes , busycount=10 voltages values after the gsm signals hangup are correctly indicated as being 48V.
You can set it to detect hangups via tones in zapata.conf with the busydetect=yes and busycount=10 entries.
It's not as clean as a battery drop (Disconnection Supervision) but hey, at least it works! :)
Although, I still think that there is some kind of incompatibility or battery drop timing problem between Asterisk and the Nokia 32. I wish I knew more about telecomms and wcfxs.c to fix it!
By changing the opermode to FRANCE I was trying to affect the electrical characteristics of the FXO module, hoping that the correct 48v would show up in the log files when asterisk hangs up. Seeing that it is now in "busytone hangup detection" mode, the values in zaptel.conf should have a influence on how it does the detection.
The changes in zaptel.conf will just change what tones (i.e. Hz) and what cadences (i.e. ms) are used to detect hangup via tones. The opermode switches should change the line impedance etc of the module.
The recordings I am after are of the hangup tones that the Nokia is producing.
Hum.. any idea how I can record these busy tones? Or is this just a waste of time, seeing that asterisk correctly hangs up based on busy tones?
Hum.. USA is not on the list of supported countries. Most european countries are, so I just randomly choose France (after hearing about nightmares with CLI in UK mode!) seeing that zaptel.conf supports defaultzone=fr .
However, seeing as you say it can make multiple tones, it may be easiest to set the Nokia to create USA tones, and then in zaptel.conf put loadzone=us, defaultzone=us and in zapata.conf busydetect=yes and busycount=10.
Although this is really a work-around to the problem (the real problem is still out there) I thank you very much for being so helpful!
Thanks,
