I notice there is a green/white wire hanging loose in the Main BT Box. Should it be? I am trying to discover if this is why there is a problem with the noisy phone line. Please note that the main BT Test Line is working however once I plug phone in to ADSL Broadband box it is then that I have problems. My Broadband provider state it is not their fault and BT wish to charge me £200 for an engineer! PLEASE HELP. Very much appreciated.

if only happens on certain calls it could either be the handset itself, a week point on all corded phones is the cable between the handset and the body of the phone. whilst talking to someone on a call wiggle the cord where it enters the handset, does it crackle if not do the same where the cord enters the phone body, if no crackle likely not phone.
next select a line if you have more than 1 line note which 1 and dial 17070. this will BT autotest the line. if more than 1 line on system do same for all lines. check with your system admin if there are quick codes to select individual lines, eg dial 9 for any line or 81 for line 1 82 for line 2 etc .
if you get crackle still on 1 of the lines get your maintainer to check the lione at the cable head where lines enter building
I had the same problem when I purchased a 710 for my mother in law. Worked in my house but not hers. The phone does not come with a BT box to phone connection line so that was a clue. Through a process of elimination I discovered that her connection line did not work with the 710, although it was ok with her old phone! I purchased a BT to RJ11 line extension lead from Maplins - all is now ok. I can only assume older connection leads are different than newer ones!
green wires and red wires.......... that is line one. also solid blue and blue with a white stripe is also line one..... so tie the greens and blue w/white stripes together and tape off (if not screwed down to block), and do the same with the red wires tied together with the solid blues.
yellow and black is line two.....and so is solid orange and orange w/white stripe. then just fill in the blanks as stated above. its simple, think of the wires as speaker wire in a way to simplify what you are looking at. multiple Pairs (+/-) wires color coded. if the wires came off of the screw down posts, just match up the colors like stated above on the posts and screw them back down.
sorry dont know if it was sent so i will do it again, i had same problem on a network and was advised to cut out the yellow resister in bt point ( only if a trailing socket NOT the main bt incoming socket), also have you got broad band modem ? if this is not on incoming bt socket this can cause problems? dont plug it in a extension lead use a proper cable and box on wall and plug modem direct into socket with no adsl filter ! next plug all your telephones into bt sockets through the adsl filters make sure you havent got to many phones plugged in this inclueds sky box which is a phone ?and needs adsl filter ? hope this helps leighton
The phone company just brings the line to the demarc( the box on the side of your house) go there and if it is a new style box there will be a place to unplug the house and you can plug in your phone. If you have dial tone and the "demarc" the hose wiring needs to be strigtened out, if you do not have dial tone and the "demarc" then it is the telephone companies problem. It is much easier to test with a corded phone if you have one , good luck
Unplug all phones in your house- all of them. Wait 5 minutes then plug a phone in a try it again. You probably have TIP n Ring reversed ( Red and Green wires) or your hookswitch on the phone is bad. If you do get dialtone after you wait 5 minutes and can hang up and get dialtone back get a new jack and try that ok
Your wiring could be a mess of splicing, jumpers, additions over the years. It's impossible to know (or to really be able to help you) without being there in person.
Typically, you just have to worry about the red and green wires. The black and yellow are for a second line. This is of course only if you have standard 2 pair wiring.
If any work has been done recently I would concentrate on that area. If just one jack is removed or a wire cut by mistake that could easily take out your entire house. Also, if the red and green wires are touching anywhere that would also cause a problem.
