The ham phone patch stuff, while it likely will contain some rather nice audio transformers, would likely also have to be modified to work with soundcard input and so would be outside the scope of this thread IMO. Besides that, there is the first hurdle, that of finding one that is still working or repairable, then comes the necessary modifications, by the time all that was done it wouldn't be worth it IMO.

And not all of 'em were designed to do fullrange audio, because they didn't have to do so.

The stick-on rubber suction cup induction pickup would be the simplest way to go here, with an adaptor to connect to an already existing recording mixer into the soundcard. Don't be misled by the low cost of the things, you get the fullrange of the phone without electrically hooking to the phone line, plus you get complete electrical isolation - no chance of Ground Loop prob. there, plus the fidelity is as good as the phone line can provide. These thijgs were used by many a commercial broadcaster back in the day, because they are cost-effective and able to get the job done.

If you really want the inductive pickup to sound GREAT, find an older *original* telephone model to use it on. Here in the states, that would be the Western El;ectric model 500 or equivalent. "Old reliable" as the commercial used to call it, those things are built like tanks and have some really great audio for spoken voice/telephone recording purposes. A plus is you can throw one through a plasterboard wall and pick it up and still use it as a telephone again...
