Off-topic informational anti-spam anecdotal

Ok, so given that there are people out there who know about phone
systems, how would I build a device that sat on the phone line and could
detect whether the line was in use or not - it's extremely annoying when
you have a modem and voice phone on the same line and your voice call
gets interrupted by a burst of modem noise! :)

btw, this is for a UK system - I've seen curcuits to do exactly this
job, but they never say whose phone systems their designed for, and I'd
imagine that US and UK systems work with different setups....



(ok, so it's not on-topic - thought I'd ask though before this thread
disappears :)
