Why do I hear myself as an echo on the phone sometimes? Just certain
calls do it. I get this on my cellphone more than my landline, but I
have gotten it on the LL too. Sometimes the echo is so loud I have a
hard time making the call. It just happened on my LL when I called a
local business. I know that business has their LL connected to a
satellite along with their tv. (My LL is wired). I get this on my cell,
at times whether I call another cell or a LL.

This echo is my own voice and it's heard about 1/2 t one second after I
speak.
That happens when VOIP is used (sometimes) and many cell phone links
are VOIPed to the landlines - also many companies you may be calling
use VOIP.
Not all voip echos, and those that do don't always.

I use Voip at home and at work - most of the time it is great.
Occaisionally I get an echo - and occaisionally on my cell as well..
It happens when the "side tone" is delayed.

When one has Comcast cable, and Comcast telephone, is the telephone
VOIP?

Yes. The cable company sure didn't string it's own copper wires.

You're probably right about Yes, but as to asking the question, there
is a lot of sharing going on. Many utilities use the same sewers.
The cable, phone, and electric companies share the same telephone
poles. UPS uses the USPS to make the final step of delivery of many
packages. Phone companies change from wires to light back to wires
again. And just like Cow wasn't sure, I needed to ask and make sure,
before I said anything to a friend, Miss A, who has trouble with her
comcast phone.

Does Comcast ever deliver quality phone service? IIRC, she gets
staticky connnections and dropped calls,.... and other problems?

Does it matter that she's on a dead-end street with 10 or 15 neighbors
all of whom probably share her comcast cable? I've heard that
sharing makes quality go down when it comes to cable? Should they
run another straight shot from the comcast local central office?

Copy to Miss A, who should reply with any other problems her phone
has, and should consider that she almost surely has VOIP in her
dealings with Comcast. And should find out if Comcast is capable
elsewhere of delivering quality phone service.
