I've not heard a hangup tone myself and I've never enabled disconnect tone 
support... Just checked on my home line (bog-standard BT line) - calling 
from a mobile and from another VoIP account - Asterisk detected the line 
hangup almost immediately... However my systems are tried, tested and 
trusted asterisk 1.2 and Zaptel.

If I don't answer it, but hangup, it does seem to sometimes take a second 
or 2 to detect the hangup, but I'm not sure if that's just BT.

Analogue lines. Bah. Hate them. Use VoIP.
