how to rewire a rotary phone to be able to hook in to a modern phone jack?

 I have a what I believe you call a cradle style rotary phone of unknown year or make, model is "the cutie"and was made in Japan.Would like to modify it to hook into home phone jack. Either by replacing the existing phone cord or adding jack to existing cord. Cord has 3 wires one green, one yellow + one red. Green and yellow are connected on to same post @ cord end ( post used to hook into wall) red into the other post.Anything else needed to get this phone  ringing let me know.

The color coding hasn't changed, over the years. Green and red are the primary line; green from the phone connects to green in the wall and red connects to red. It probably isn't actually using yellow.

If it has the old four-prong plug, there are adapters which will convert that for the modern modular connector, or you can splice on a modular cord. Of course you can also splice if it has bare wires.

Issues:

1) The electromechanical ringer in that phone will draw much more power than the electronics in a modern phone (ie, it has a higher Ringer Equivalency Number). That may limit how many other phones you can have connected on the same line, unless you open it up and disconnect the ringer. (Which is what I did with a Truly Ancient phone in my collection, whose ringer I simply didn't trust.)

2) Last time I checked, while Telco still supports pulse dialing, they really don't like people using it. (And they like switchhook dialing even less.) But as long as they continue to charge us a surcharge for the "speed and convenience" of touchtone service, I officially consider this Their Problem.
You're not serious about charging for touchtone are you ?
Wow .

Yep. Basically, nobody in a position of authority has forced the phone companies to admit that they're charging extra for what is now the norm. It's a small fee (fifty cents in my area), but over enough time and enough customers that's a large amount of additional income.

One other thought to ponder: Back in the day of rotary, most phones were _rented_ from the phone company rather than purchased. So, technically, you may be in possession of stolen property if you stopped paying that fee but didn't return the phone and didn't purchase it. Not that telco is likely to care at this point.
