Srictly (where I am at least) anything connected to the phone lines needs to
be approved. Aside from that, you certainly wouldn't want to earth one side

when the line goes on and off hook the loop voltage goes between maybe 50
volts and a quite low value, and you need to ensure that whatever you attach
isn't damaged by the transients. Also, AFAIK the level of the send signal on
the loop can be significantly higher than the receive signal, meaning that a
straight off line signal may not record well for all speaking parties -
normally this isn't noticed because the bridge in the phone takes care of
it. Your easiest option is to purchase something that does what you want and
