RE: Telephone systems
Telecoms operatives still use those handsets nowadays. Standard stuff. Tis one of my professions[/u]. I have a few knocking around my place;-) Well built bits of kit that last for ever and you can monitor calls without being apparent on the line.
A normal phone will not ring out upon receiving a call on the line (not an issue if you are just making a call) unless it has a master socket it is plugged into or it is in an extension socket with a 3 wire connection. The test phones all have capacitors built in that enable them to ring out on any 2 wire connection. TL.
