Telephone cabling to a telephone slave socket

I want to position a metal back box within a stud wall and then bring cabling up to the back box so that eventually a flush slave telephone socket can be attached to this back box after the wall has been boarded.

I want to run telephone cabling within the stud wall up to this back box. I'm not connecting it to the slave or the master socket myself - I just want the cabling within the stud wall before it's boarded then get a professional to later connect it either end.

Specifically what type of cabling should I run from the master to the slave socket? Should there be a specific type of plug on the end at the master socket or perhaps the professional installer can attach a suitable plug later?

Thanks.

Just a word of warning, broadband can be negatively affected by extension sockets, even just the one. Any broadband routers should be plugged into the master socket. Also why not go cordless phones? You do not require any extension sockets then.

Power cuts ...

... unless the cordless phone 'base unit' has battery backup {which none of mine do}.

Kind Regards, John
Our Current Panasonic cordless 'phone "base unit" is powered by the "hand unit" sitting in it during power cuts, with the other two "hand units" being usable.

While the earlier model "Panasonic" did not have a back up battery, I provided it with one with NiCd rechargeable batteries on "float" across the power supply.
Just a "box" to contain the cells, appropriate plugs and sockets, three "steering" diodes and one resistor.
One needs to calculate the number of cells so that their fully charged voltage is just a bit below the supply voltage, calculate the resistor/diode combination which (under these conditions) will provide a "charge" at about 1/100 of the discharge rate into the cells, and wire the two other diodes so that, when the supply stops, the battery powers the Base but current cannot flow "back" into the power supply. (The latter diode is probably unnecessary, but it seemed like a good idea.)

This "back-up" supply was in use for over 5 years and, during this time, was tested once by a power failure of over 12 hours, through which it lasted.

I would imagine it could be adversely affected, but I have approaching an extension socket in every room and I get full speed from my fttc.

No reason to have so many sockets these days though, because as you suggest - cordless phones are very good these days. Always best to ensure you have at least one standard plug in phone somewhere though, for when there might be power cuts. I have one hidden in a kitchen drawer, ringer switched off - it remains plugged into a socket at the back of the units.
 
Fit a filter at the master socket - and if you want the router to be elsewhere, use a spare pair to route the unfiltered line to another socket. So, you would fit the master socket with the sandwich filter, or service specific face plate for the latest type, then use the blue and orange pairs for the filtered phone service, and the green pair for the unfiltered line to the router. You can buy faceplate with one phone socket and one "RJ11" socket for just this sort of setup.
