Hi, every time I try to call my house phone or someone tries calling me it says the line is busy but no-one is actually on the phone. How do I stop it from being busy because I'm afraid of being charged a huge amount for a phone call I'm not even making?
have you tried connecting your phone to the test socket and see if that cures the problem
If the Test Socket works then there is a problem with something connected at one of your extension sockets. Unplug everything else from the extensions sockets. That includes your sky box, broadband router, fax machine as well as all other telephones.
Replace the faceplate and connect your phone to the faceplate socket. Does it still work? If so, plug everything else back into its socket one-by-one. Test each time until you again get the engaged tone on incoming calls. Whatever you last plugged in is causing the problem.
The problem is that a BT engineer may charge you a hefty amount if it turns out to be faulty wiring rather than a faulty faceplate because the internal wiring belongs to you and BT will not fix it for free.
