I can't find a suitable group to ask this question but......

I am considering using the internet for my phone service (Comcast) in place
of my present one (Verizon). With the same features, the cost is
considerably less.

Looking for opinions from anyone with internet phone experience as to
performance and reliability.

A friend of mine has Comcast phone service, he seems to
sound fine on it and said it works ok except when there' s a
cable problem that knocks out internet access too. After he
had a technician out and that tech had a repairman followup
to fix the cable problem everything was good again.

In other words, cabling up to and at your location is a big
variable. Some people have really old cabling around and it
is prone to occasional dropouts. IMO, in general cable
company cable (fit enough to maintain digital transmissions)
is more likely to degrade enough it needs repaired vs POTS
cable, but today so many have cellphones that the issue
isn't as important as it used to be. If you already have
Comcast cable, you already have a good idea how often your
signal is degraded or completely interrupted.

We have had hardly any outages with my internet and TV. But I wonder about
the quality. I just got HD and a DVR from Comcast and a tech had to come
and replace the box...was glitchy. All is well not but he did say the
signal level was a little low but acceptable. Makes me wonder how robust
the phone service would be.

We have the Digital package and once in a while the picture pixelates and
recovers within a second. That now gives me something to think about.

Regarding the occasional outage, my cell phone would fill in until power
returns.

Thank, Dave C.

They are required to have a certain signal strength at the
box outside your residence. Anything inside you can deal
with by a more direct route, using fewer splitters or
putting those for TV after a video amp. A little low is
vague though, you'd have to wait and see how it works.
Basically, if you get it hooked up and after a reasonably
required single splitter to the phone and modem it isn't a
strong enough signal, they'll need to come out and rectify
the problem.

Pixelated images are usually due to excessive compression
not signal quality. Signal quality issues tend to cause
freezing or blanking out entirely.

         I have Comcast phone, TV, and Internet. Although it was a problem at
first, they found a bad connection in the feed and eventually it worked
(and works) fine. It seems the phone is on a sideband that is of a
lower frequency and the problem was only noticeable on uploads for the
Internet and the phone service. Downloads and the cable TV were unaffected.
