I currently own my own modem that is for internet and voice (Arris TM822G). I upgraded my internet to the 600 Mbps tier and need to purchase a new modem to take advantage of the upgraded network speed. Can I have separate modems connected to my cable feed (in different locations in the house) for voice and for data? Would I be able to keep my old modem for voice only and save a bit of mony by getting a new modem that is just for internet?
