The talking part is easy; the ringing is not. If you connect the two phones in series with each other and about a 6 volt battery, a conversation can be had. But ringing requires a source of 20 Hz current, at about 90 volts, and this is hard to find. You may want to set up a separate doorbell or buzzer circuit for signaling.

I ran across this a few years back.
You will need to figure out some way to send AC current down the line to activate the ringer.

2 outdated females outdoors a eating place. One outdated woman says to the different "Did you return on the bus?" to which the different one spoke back "specific, yet I made it look like a stroke." Your shaggy dog tale jogged my memory of this one.. V. humorous.
