Thanks a lot for the helpful info...  I think.  I am still not clear on 
where to configure this.

Are you saying that the "busy" tone is the tone used to force a hangup? 
  I guess this makes sense,  but I guess I thought there might be a 
special unique hangup tone(shows what I know).

Anyhow,  your information has driven me back to the documentation 
(ouch) and I see that command line serial port configuration actually 
has options that are not available at all through the web interface.

So tonight I hacked up a serial cable (for mac) and fired up a terminal 
session on an old Powermac 9600 running 10.2.

This allows me to use the command line configuration,  which includes 
both a polarity reversal option (sysconf -onhook 1) and also has a 
method for actually recording and analyzing the "disconnect tone".  I 
have enabled the polarity reversal option, and that looks good at 
present.

So, thanks again for your insights into this device!  Any ideas on RFC 
2833 DTMF issues I am having ?

  ;~)

Thanks,
