Hi there. Phones certainly aren't my thing - but I am trying to put two analogue phones into a building which has a patch panel.
There is only one line - a standard telephone line. But I want two phones - one upstairs and one downstairs. They both need to be on the same line. If someone is talking on one phone and someone picks up the 2nd handset, they will be having a 3-way conversation.

I've managed to get one phone working - by patching the phone line to the relevant port at the patch panel and then I've plugged the phone into an NZ Master Socket to an RJ45 plug - all good.

What equipment should I use to connect up the other handset on a different patch plug?
Do I use a plain old double adapter at the patch panel and find some cables which go from NZ Master Socket (male) to RJ45 (male) - do they exist? Is there another way which I am missing completely?

It's been a long week....

Thanks in advance.

Does the phoneline originate on a RJ45 port on the patch panel or a BT wall socket?

If it's installed properly on the patch panel the easiest way is to buy an RJ45 splitter which you plug into the port that has the line and then run 2 x cat5e patch cables from this splitter to the 2 ports on the patch panel where you require the phones.

If the phonejack is a BT wall socket then the easiest way is to use the same setup as above with a custom made inline RJ45 socket to a BT plug. You can just use a BT double adapter and use 2 regular BT->RJ12 plugs plugged straight into the patch panel but permanent use of RJ12 plugs in RJ45 sockets isn't recommended as it can cause damage since the 2 outer pins are not used.
