I currently have a modem/router combination that has worked well for me. I am moving to the triple play package that also includes voice. I am curious if I can purchase my own modem for voice as my current modem/router combination does not provide that (Motorola SBG6580). I have reviewed the link displaying approved devices http://mydeviceinfo.comcast.net/. However it isn't clear to me if any one of those can be used as voice only. And/or if I can have two separate modems, one for modem/router and a second for voice.
Thank you.
