I wouldn't have posted without having tried that beforehand.

The problem persists with both busydetect and callprogress disabled.

In Japan. Lines are provided by NTT. The driver (wcfxo.o) has been
built with "#define JAPAN" uncommented. Before the present 1.0
release, this has usually reduced false hangups.

No.

Fair enough. But then again, why not have an option that disables
hangup detection until a call actually goes to voicemail and leave it
disabled if it doesn't?!

Anyway, so far false hangups with Zaptel on Japanese phone lines have
been mostly a sporadic problem, but with this release Asterisk hangs
up *every time*. As I have said in my earlier post, the same hardware
did not have this problem with CVS from about a month ago (August, 19
or 20).
