If recording from a standard telco-line telephone, the device of choice is the stick on inductive Phone Pickup. May be getting hard to find these days.


Avoid attaching wires directly from phone line to soundcard, while it may look like the way to go, there WILL be isolation problems as well as the fact that the Ringing circuit is like 90 volts AC. There are audio transformers designed to connect directly to phone lines like that.

What type of phone system will you be recording?

That is important to know before describing the proper way to capture the sound from the device(s).
