Recommendations for phones, please

Hi everybody.

We live in a rather large house with stone walls up to 1300cms thick.

We need to replace our ageing phone and would like advice on what to get before buying and finding the signal won't stretch!

We use a router and are de-groupee, so only one phone socket will work. The rest of the phones need to operate cordlessly around the house which has several lots of fuse boxes so I don't know if I can use a repeater or three?

Any advice or recommendations welcomed!


not 1300 cms thick - that would be overdoing it some!

Rather, 130 cms - I got my centipedes and millipedes confused!
