Where can I find a recorder that will record all conversations from land line?

Question

I have only seen some recorder controls that record conversations only from one land line. Where can I find a recorder that will record conversations from every land line in my home?

Answer 1

There are in the market multichannel recorders. They use them in army in police or in some companies.

I know a company Stancil in USA and ATIS in Germany.
