Years ago I made a Pascal program that made an external modem (2400 baud!) dial and then switch to voice mode. If you're using dial-up your phone is connected to your modem and you could probably try that. There used to be a javax.comm package ... don't know if it's still around or supported or what.
If you're not using dial-up and not using a modem then I don't know how your standard phone would be connected to the computer at all.
If you're on IP-Phone, you can probably get a SoftPhone kit from your provider.
Any of that sound right for you?
A good question is never answered. It is not a bolt to be tightened into place but a seed to be planted and to bear more seed toward the hope of greening the landscape of the idea. John Ciardi
