It's simpler than you think. You find your cable modem and then call Comcast to ask if they will accept that one on their system.

I am going to purchase a replacement modem for use on my Comcast Internet account.
I know I need DOCSIS 3.0. My company has provided me with a Cisco VOiP phone that ties into the company phone system.
Do I need EMTA or will a modem without EMTA do the job? I won't be using Comcast voice.
If I do get an EMTA capable modem, do I connect my phone using an ethernet connection or is there a special connect for EMTA?
