Cable's Roadrunner internet? ok, i have the full package from Time Warner Cable. i have cable, internet, and phone. well, the phone line comes out of my modem, and then connects to all of the phones in my house. is there a way to have caller id on my computer without connecting a phone line to it, since the modem delivers my phone service? this is my own personal computer, so i can download things, which i hope will make it easier.
