Yes, it's called Skype.  You of course need a dial-up ISP.  A bit o.t.

Last time I tried running Skype in Fedora it worked fine, though I 
wasn't using a dial-up.  They had the best voice quality of any VOIP I 
had tried at that time, meaning, better algorithms and better chance of 
success under dial-up bandwidth.  It's been a couple of years, though.  
Not sure if the stock Fedora even comes with the dial-up software any 
more, though probably easy to install.

Come to think of it, it shouldn't be such a bandwidth hog, digitizing 
voice then presumably compressing it to near its Shanon entropy.
