BT Phone not working here in Dublin

kaner69

Hi all

Brought a BT phone back with me from the UK a few weeks ago, tried to hook it up but it is showing "no line" on the screen. Had a look on here for advice from previous threads and the suggestion was to buy a BT to RJ11 adapter which I bought this morning, however it is still showing "no line"

Any advice on this would be appreciated

Plug in a KNOWN WORKING PHONE to where you are trying to plug the BT phone in to.
Make sure that the RJ11 to BT adaptor also has a ringing capacitor fitted.
In RJ11 (Ireland/US and a lot of the rest of the world) the line is on the center 2 pins.
In BT Land the line is on the outer 2 of the 4 pins.
Also in BT Land the incoming ringing works because there is a Ringing Capacitor of 1.8micro farads or so built in to the master socket.

thanks for your reply
already had a phone in and working, this one broke hence the change, RJ11 adapter has the capacitor in it (made sure of this when I got it yesterday) however it still won't work so not sure what to do

Xantia

Was it working when you were in the UK?

kaner69

Yes all was fine in UK, both phones were paired with the units

Xantia

Oh - so they are DECT phones?
They may need to be paired up again.
Also it's worth trying to plug in an Irish RJ11 lead into them.
They could been RJ11 (Irish) type by default and in UK were using crossover leads.

Ok thanks for your help, I'll try that tomorrow when I get home and hopefully they will work

Xantia

A lot of the early BT DECT Phones were Siemens but branded BT so it's possible that they would work straight off with an RJ11 to RJ11 lead.
Give it a try anyway and let me know.

Will do thanks again

Had a look at the user guide this morning and there does not seem to be any mention of pairing the phones. Also tried the RJ11 lead I had with the old phone but still getting "no line" on the main display. Not sure whether it makes a difference or not but the phone line is going through the UPC modem so I am at a loss as to what to do next

Found the problem and got it sorted, the lead that was in the box only had 2 pins terminated, so I found another one and phones are now working, thanks for your help Xantia

Great.
I should have mentioned that -
The original BT plug system needed 4 wires.
Outer 2 for A & B legs
one for the bell ringing from the capacitor in the socket and the last one for an earth in the old days of earth recall.
