How good is your cable modem connection? We have all come to expect very high availability for phone service, does Comcast meet that for IP in general? The question of VoIP provider is a second issue. I have used Vonage and they seem to be excellent. I have also used iconnecthere.com for some outgoing calls and they seem very good--though I am mostly using them on a poorer internet connection so I might have suspected them in problems for which they were faultless. Third is your own infrastructure. Will you have your cable modem, routers, and VoIP hardware all battery backed up? (With a long enough battery life?) When you mess with your own router will you possibly play with the nifty quality of service features or firewall rules and get something wrong? As a customer Plain Old Telephone Service is simple, and that makes for reliability. VoIP isn't as simple. I recently turned my Verizon service down to the lowest and most metered level possible and am saving a lot every month. (Previously I had unlimited service selected in dialup modem days.) Every call is metered, but we don't use our wired phone much for outgoing calls, so I think the metered portion of the bill has been under a dime every month. At some point we might do the number portability thing to switch our home number to Vonage, but I expect we will keep some wired service. If nothing else, our Covad DSL is very reliable and it requires a voice line. Vonage is cool in that it will ring multiple numbers simultaneously, or when the Vonage box isn't online send all calls to some other number. iconnecthere.com is nice because they will let me use my own hardware (or software). -kb
