However the consumer unit was not labelled up with telephone lines etc. I have however found a store cupboard with a BT box thats all the phones seem to go back to that is linked to the circuits I have isolated. Is there a reset procedure when power is switched on and off from the box?</P> Sun, 25 Sep 2011 12:03:09 GMT buzz 2011-09-25T12:03:09Z https://business.forums.bt.com/t5/Archive/Telephone-problem/m-p/30431#M16462 <P>Hi I am an electrician, when working in a commercial premise I have found that all phones are not working after I isolated the supply to work and test installation.
