echo using bluetooth headset with anycom usb-100

Hi,
using a bluetooth headset with an anycom usb-100 dongle for phone purpose
always results
in lots of echoes similar to using a non-full-duplex sound card.
Is there anybody out there who knows how to avoid this effect ?

Thanks for any advice
Dietmar

What headset are you using?

In that case quite sure the problem is within the Anycom device. If you are
able to control the gain of the microphone (though unlikely!) and set it
lower this would help.

Well,
I really don't know how this is supposed to work. I can change the
microphone gain,
or even switch it off without any effect. Maybe, this is somewhat "works as
designed".
To help me decide whether to do some more analysis or give up, I really
would like
to know if somebody has a similar configuration, but does not run into this
problem.
