How can I tell who "owns" a telephone line

[Halcyon]

I have two telephone lines coming to my house - the previous owner had an extra one put in as a business line.

They've been here since I came 2 and a half years ago, but I only use one for telephone and broadband (talk talk), it had never occurred to me that the business line might be live, but whilst messing around with my router yesterday I plugged the phone into the business line and it's got a ring tone. left it plugged in for an hour or so and got a spam phonecall on it.

Anyone got any idea how I can find out who the provider is or whether I should bother?

Keep using it - someone will eventually send a bill.

BT still own all the phone lines don't they?

Phone them up and ask?

[original PM]

yep BT do still own all lines - stick a phone in the socket, ring BT and ask them if they can identify you

maybe

I know somebody who lived in a house and who the electric comapny would not admit that their house existed even though they supplied them. They had 5 years of no bills.

Ring you other line from it to find out the number and then bung the number into google and see if it can find it. There are some reverse enquriy sites as well which might find it.

Same happened to my brother ... plug the phone in and keep quiet! If you were due to pay they would have sent a line rental bill ...

cheers y'all. I tried googling it, I don't have to be too clever to identify the line number as someone kindly printed it on the socket

I suppose it's just another big corp that hasn't got a clue what's going on with their customers

I did a quick job for a teleco once sanitising a database of where they had installed their equipment - whoever set up the original system put a free text field for customer name, you'd never believe how many variations of "Siemens" there were in there

On one contract I was sitting with a girlie who spent 3 months ringing numbers - only to find...

"Oh, your in the security hut of a building site?" or "It used to be a sports and social club of XX company?" or mostly just ringing out...

She saved over £11k in line rentals per month ongoing.

Here is a tip!

Call the BT test number 17070 from the phone - The robot voice will read you your number back.

If the number is withheld - just put 1470 in from of the number - 147017070
