Tonezones ar eirrelevant to disconnect supervision.

Likewise is the opermode .

A. Any chance some other method of disconnect supervision works for your
line? Polarity reversal? 

If you must depend on busydetect, try one of the following:

* Playing with the value of progzone . Not too many options, but still.
  If you're really in the mood for patching, creating an appropriate
  progzone of your own would be nice. Look for prog_mode in main/dsp.c .
* Alternatively, try playing with the 'busypattern' in zapata.conf .
