Echo issue on OM2008.08 solved

[Daniel Nöthen]

Hello,

I finally found a place in the qtopia sources where I could put code for 
activating the
echo suppression for every incoming/outgoing call.
I'm quite sure that experienced qtopia programmers would find a better 
place for it.
But this just works. And as long as no other solution is out there I 
will share it
with other people who want to combat the echo.

The patch is against the latest snapshot of Holgers qtopia git.
commit: 09335e76e1762b97dad23b997978424ed10f8da1
Unfortunately this version doesn't load the gmshandset.state file when a
call is initiated.

When compiling with this patch a new libqtopiaphonemodem.so.4.3.2 is
created. I replaced this lib with the one on my OM2008.9.

Instead of compiling it yourself you can download the file here:
http://danielnoethen.de/libqtopiaphonemodem.so.4.3.2
Just replace it with the one in /opt/Qtopia/lib and restart qtopia with:
/etc/init.d/xserver-nodm restart

In combination with this gsmhandset.state file the volume of your
calling partner is loud enough, and vice versa.

It should work with every distro that uses qtopia-phone-x11_4.3.2

Regards,
Daniel
