Thanks John, but I still get the problem with 1.6. Looks like the VoIP
plug on my ADSL modem doesn't provide either polarity reversal or open
loop, so Zaptel/Dahdi can't dectect answer/detect.

Could be on purpose, to prevent people from hooking up an IP PBX and
use this option in ways the ISP wants to prevent ;-)
