Has anyone else been experiencing echos during voice calls? This started
just recently for me in the western PA area and I find it extremely
annoying.

Do you have the latest firmware version? I recall that at
least one firmware version on my Sanyo 4900 was specifically meant to
address echo problems in certain areas.

This has been attributed to faulty echo cancellers at the tower, except
I have found this to vary by phone. I used to experience this a lot on
Motorolla phones when I used Verizon several years ago.

Here's a little bit of information about Echo Cancellers

http://www.arcx.com/sites/EchoCancellers.htm

They're in the provider's switch, which serves a part of a metro area,
not in the individual cell sites.

Forgive me - I just checked. I'm on 1.056 and she's on 1.057. 1.057
was the one that purportedly addressed the echo, and I didn't upgrade
because I had no such problem. Hers is a refurb/replacement that came with
1.057 installed. And you're right, there was no 1.058. I had my numbers
mixed up. 1.059 is indeed the one that addressed roaming problems in
Virginia.

I don't believe that phone software has anything to do with echo
cancellation, but then, what do I know.

There are no echo cancelors at the tower site. Echo canceling is done at the
switch.

Thanks. That is a nice reference. What I was referring too actually,
was that echos are not generally caused by the handset. I was not aware
that echo cancelling was done at the switch rather than the tower
however, so that is very good to know indeed.

In the case of the Sanyo 4900, you are 100% wrong as there was a firmware
update to mitigate that issue.

Hence the word "generally". Still, I can't find any reference to this
fact other than a suggestive implication by David G. Imber. Do you have
something better?

I get this once in a while. oddly twice in the last week. makes the call
unusable. I have to hang up and call back.

I have never gotten it on an outgoing call. just incoming and its bad (sanyo
6400)

stopped now and has not returned but then again I do NOT use my phone that
much. i have 400 anytime minutes and I have to work hard to use them all up
🙂 really hard 🙂
