BT Versatility Phone System
One of my schools has a small exchange box with a couple of BT Versatility V8 phones attached (along with an assortment of "normal" machines.
They wanted an answerphone, and bought a £35 job, but the only lines that ring have the V8s attached (and the phones can't be moved). The problem is that once they are plugged into the answerphone, they don't work; I suspect that it's a power issue.
So my questions are:
Does anyone know the voltage/polarity requirements of the V8 phone (there's a power socket underneath), or does anyone know if there is such a thing as a default programming code for the phones (so I could activate the ring on an extension)?
Really want to avoid the £100 minimum for a BT engineer...
