said by BiggA:If you care about reliability, you'd get a copper landline. If you care about price, you'd get Ooma or something like that. CDV just doesn't have a place in either.
I disagree. I find that Comcast CDV has been absolutely reliable. Yes, if your power goes out, you will have a shorter run-time than with a landline...
assuming that it does not go out, and I have had loss of landline service a couple of times due to outages in recent years).
Obviously, based on location, YMMV with
either a landline or CDV.
Price, I do agree on. There are cheaper options that have varying degrees of call quality as well as reliability...but that is the price for saving some bucks.
