[misterhouse-users] Phone in Use/Interfacing with Misterhouse.

[Stuart G. <st...@sm...>]

Sorry to send this to both lists, but the questions are relevant to both...

I have been looking at the phone circuits on ePanorama
(http://www.epanorama.net/telephone.html), for checking if a line is in
use. Firstly, would and of these circuits work in the UK? Does anyone use
anything similar?

Secondly, what I want is for Misterhouse to be able to tell when the phone
is off the hook, and to respond to voice commands when it is. Is there any
way to tell when the phone is just off the hook, and when an actual call is
taking place? Are the voltages on the line different?

Otherwise, I think I'll be using the universal command prefix that was
introduced to Misterhouse recently, what version was that Bruce?
