Hi,
I have a SPA-3000. My telco sends no disconnect indication
whatsoever, so I am having trouble making the PSTN line detect
disconnect.
What I want it to do is detect the very loud off-hook tone that is
generated about 20 seconds after disconnect. It's not perfect, but
it's a lot better than silence detection. I noticed that the zaptel
drivers can detect this with busydetect, but the SPA-3000 can't seem
to.
I suspect I need a new value for the Disconnect Tone in the PSTN
configuration, but can't seem to concoct the magic potion. Google and
various forums aren't helping out either.
Any suggestions?
