No, but very doable, and of dubious legality, because the phone is also a
type approved radio transmitter, and the mods would most likely void that
type approval.  Still, an interesting idea.

The way around that issue would be to interface the PC to a phone line
simulator, which the phone plugs into.  Hmm, how easily could we simulate a
phone line using a PC and some add on hardware?  Gee, you could have busy
signalling and all, if the software supported it. :)  This approach would
also allow the use of unmodified landline handsets.
