Req circuit to record from phone line (UK)

I'm in the UK. I want to record my landline phone calls.

I once made a crude device which had a transformer (don't know its spec). A pair of wires from one side of the transformer went into the telephone wall socket and a pair of wires on the other side of the transformer went to a jack plug which goes into my recorder. There's a potentiometer adjusts the output level.

It kind of works but not very well and I get too much hum.

What would be a proper circuit to follow?

Even better, is there a non-expensive recording adapter I can buy in the UK which plugs into the phone wall socket?

This is posted to uk.telecom and to some elctronics groups.

I find this is quite sufficient...you interpose it between the handset and the phone, by unplugging the handset cable.

A search term that might help you is "phone hybrid". That's what we call these audio-to-telephone interfaces in the broadcast industry.

They have loads of products (but not 'inexpensive')

I've used several of the JK Audio 'THAT' range (THAT-1 and THAT-2).

The THAT-2

For recording from a telephone, you need low background noise and good balance between the near and far party. Check out

which sounds like hi-fi even on an ordinary telephone call. There is a description at

with sample files that you can listen to. RuthWest
