Vintage touch tone phone receives calls but won't generate tone.

I just bought this 1977 ITT K-2500
touch tone phone for $5 from Value Village. The phone rings and gets dial tone and sounds crystal clear when you receive a call, but it won't dial. When I push the buttons the dial tone gets quieter but there's no tone from pushing the button.
From the limited info I've found on Google, there may be some kind of issue with voltage or polarity or something, but reading wiring schematics (this one can be found in the link above) is not really my forte. I can open stuff up and use a soldering iron, but am clueless about how phones work. Is there an easy-ish way to make this a workable phone?
