I have booked Community fibre to be installed next week with their
voip service for my landline.
I am curently using Viorginmedia BB and their voip.
My VM cable modem is upstairs and use UK telephone socket to pass
the VOIP signal to UK socket in my living room and dining room.
I would like to know can I use my CF ported land line VOIP
with same sockets?

<https://communityfibre.co.uk/landline> implies they use a Grandstream
ATA. It looks like they provide an RJ11 male to BT female cable. Then
it is up to you subject to the ringing current the ATA can provide.

The pictures seem to show the HT801
<https://www.grandstream.com/hubfs/Product_Documentation/ht80x_user_guide.pdf?hsLang=en>.
There doesn't seem to be any ringing current specification, but it
looks like it handles all the UK caller ID options.

There is a high ring power option
<https://www.grandstream.com/hubfs/Product_Documentation/ht80x_administration_guide.pdf>,
but I couldn't see anything saying what that means in engineering terms.

I imagine an RJ11 male to BT male, two wire, cable would do it to
connect into an existing slave jack.

Thanks David,

so it will work around the house.

Though it may need a cable wired with pins 2/5, or with 3/4. If you
need to be sure it'll work on day one, buy one of each type?

Thanks Andy,

how do I tell which one it is?

Usually a BT (white) 6-pin plug is wired 2 and 5. If you hold the plug
with the pins showing and away from you pin 1 is on the left, but as it
is only two wires it is academic which way round they are.

RJ11 is a six-pin housing with only the four middle pins (i.e. 2-5)
present (sometimes on prewired cables even only 3 and 4 are present!)

You can of course buy a short ready-made adapter cable with a BT socket
on one end and a RJ11 plug on the end of a short piece of cable. If you
buy an ATA for the UK market said adapter is supplied.

True RJ11 is 6P2C, with only 3 and 4 connected.

I'd assume that Grandstream devices are true RJ11, in which case the BT
adaptor would be 3 to 2 and 4 to 5.

Grandstream device just srrived this afternoon, it has a BT socket and
an Ethernet port.

CF are coming this Tuesday to setup bb and voip.
