I am running a CX100 with Microsoft Lync 2010 on a 64-bit Windows 7 platform.  The receivers on my calls (other CX-100s) all hear their echo when talking to me.  I don't have any problems on the sender end, and no other users seem to have this problem with their devices when talking to anyone except me.  I have tried turning off all other input/output devices, and turning the volume down to minimum levels, but to no avail.  Any suggestions on what to do?

Thanks, John.

SOLVED!  For some reason TTY mode was turned on.  I turned it off, restarted, and the echo went away!  The sound quality also improved!

 

Below is the Lync 2010 description of what can happen with TTY turned on:

 

"Text telephone (TTY) mode is used for text communication over a telephone line. A TTY device must be connected to the computer to interpret the modified audio; otherwise you might experience poor audio quality during the call. Using TTY mode in a conference call might also cause audio quality issues.

By default, TTY mode is turned off. You can turn on TTY mode by clicking Phones in the Lync - Options dialog box. You will then need to sign out of Lync 2010 and sign back in to use the feature."

I thought that this would solve the problems I have where other folks report terrible echo when I am using my Polycom speaker / microphone - unless it is muted or with headphones...

 

BUT the option is already turned off in my LYNC set-up, and they still report the terrible echo. 😞
