I would like to purchase my modem rather than continue renting. When talking with a Comcast rep on the phone he stated I should buy a D3 cable modem Emta to serve both for internet and phone.
Looking at Comcast list of compatable modems I see either "telephony modems" or "modems"
How can I determine which are combined for phone and internet and work with Macs? The chart is not clear on this.
