It's nice to bundle everything for cheaper but something about VoIP on comcast even with a dedicated bandwidth area still scares me... something about having two seperate services makes me feel better knowing if the cable is out I can still use a land line and vice versa... wouldn't want my cable internet and phone all going out at once personally...
My internet was out the other day for about 12 hours. my digital phone with TWC still worked. Just because you have Digital phone doesnt make the entire thing go down just because one service does. With Vonage or any other VoIP provider this would not have been true. Even about a year or so ago a major Fiber cable owned by ATT was cut in my neighborhood by a construction company. The POTS lines were out. TWC digital phone still worked. I wouldnt give it up for any POTS carrier.
If i'm not mistaken the Digital phone part of the modem is DOCSIS too. It has to provision just like the modem part by MAC address. Its just not turn it on. It gets passed a data packet to tell you what you have and what not; just the same as the modem does for speed.
I don't know how it works myself, all i know is it has its own dedicated area of bandwidth... anyways my point is I want a backup if my cable is out... its always good to have a 2nd option... like a data provider does with multiple links over different networks incase one goes out you can still communicate
