A:Answer This modem does not directly support a land line for VOIP-- meaning it is not going to allow you to plug an RJ11 satin line cord into it -- VOIP itself though will work fine - meaning if you were using Vonage, Magic Jack, Google, or any other VOIP service, it is simple a small device that you would plug into your network router, that would terminate the phone connection and handle the VOIP data - TWC ( at least used to , I got rid of mine a year ago ) pushes the VOIP calls through there own private network, so using a non TWC managed device generally won't work. I personally found -- Obihai - OBi VoIP Phone Adapter Sold right here at Bestbuy works great with Google Voice. Frankly I like the Google Voice features better anyways - and as long as you are not calling international -- its free.
