Here is one for all of you techies.  As mentioned on previous posts, I just
picked up a second Sanyo 4920 for my wife.  I've had the first 4920 for at
least 5 months now.  Before the second 4920 no feedback and no echo on any
calls. This is the best phone I have had in 4 tries including the LG
BlueTooth. However, now I can't call my wife on her 4920 without a HORRIBLE
echo.  It sucks! I hang up and call her back and the echo is not as bad. If
I call her on our home line...NO ECHO!  I call other cells, other services,
work, etc. no echo.  But I get an echo with the 2nd 4920. And Yes! I have
tried to see if the problem is her phone.  This happens if she initiates the
call also.  Could it be a problem with the 2nd phone? What else could be
causing this problem?  Is anyone else having similar problems? Same phone?
2nd user? Help me understand.
