Who has a set they like?

I just bought a Panasonic set. *I get echo. *I am taking them back to

They are 6.0

I decided on an AT&T SL82318

It has two extra handsets. *I got it at Target for 90 bucks. *An added

Hmmm,
Echo is not phone's fault. It is phone lines fault.
Actually no. * The phone line may cause echo, but it is not the only
cause.

No it can't. *The signal travels at the speed of light.
Unless you live a hundred thousand miles from the nearest town, the
propagation time on the lines will be less than a thousanth of a second.

The echo is caused by propagation delays when sending
digitized calls over satelite or within some equipment when converting
to/from digital and when buffering the data.



Actually, if you want to blame A/D and D/A conversion, the cordless
phones, almost all of which are digital now, have to do that too in
both the handpiece and the base. But regardless of where the
digital to analog converion is done, there is no reason for that to
cause echo as the delay through the A/D circuit is only nanoseconds.
And echo is not limited to digitized calls. It existed when phones
were analog as well. Poorly balanced lines that caused reflection
were one big source.

If he has it with the new Panasonic phone on every call and not with
another phone, that would be pretty strong proof that whatever he's
hearing that's a problem is being caused by the phone.
I find that hard to believe.
