Son shares his flat with four others. The original deal was to share the br oadband costs but not to have a phone connected so that there would be no t elephone call charges. This arrangement has been abused so he wants to find a way of making sure no one can plug a phone into the master socket. The m aster socket has separate phone and BB outlets
Would filling the phone outlet with Araldite work? Or does it conduct elect ricity so it might short circuit the line voltage??
If filling it works then we plan to fit replace the screw on the face plate with high security ones.
Or is there a better way?
