The Tx or Rx audio quality on my Calisto sounds muffled or distorted?

•If the Calisto unit is used by several people at the same time, users should be positioned either in front or the back of the unit for optimal microphone pick-up.

•For small group calls, we highly recommend that the PA50 Wireless Mic be used as it provides flexible 360 degree room coverage.

The Wireless PA50 Mic doesn’t seem to work as well as the Calisto speakerphone?

•First, make sure the PA50 Mic is indeed turned on (see above question).

•Second, make sure the PA50 Mic is placed on lapel in the optimal location shown here.

•It can also be placed flat on a table for group calls but in that case, more background noise/room echo will be picked up

When I plug the unit into the USB port, the unit says “PC unavailable”?

•First, make sure MSFT OC R2/Lync is up and running

•Second, go into MSFT OC “Tools/ Set up Audio and Video” and make sure

“Calisto 800 Series” is selected as the Speaker and Microphone

•Third, go to the PC System Audio Settings and similarly make sure “Calisto

800 Series” is selected as the Default device for “Playback” and “Recording” (optional).

•Reboot the PC and the unit (both USB and AC) and try again. When plugging the unit into the USB port, make sure that the “Hardware is detected”.

How do I know what version • Go in Menu> Settings> About Calisto of firmware/software I am

using?

Some keys on the dialpad do not seem to respond when I hit them?

•The keypad sensors adapt to a user’s touch as much as the user also gets used to them. Just like with Touchscreens, it may take a few hours for the user and the unit to get fully “calibrated”!

Call Control doesn’t work when I use Skype, Avaya or other non Micosoft Lync/Office Comminicator softphones?

•Call control for softphones other than Lync/Microsoft Office Communicator will be available later in 2011

When I try to redial an entry in the Call Log, I get an error message that the call cannot be dialed?

•Today Lync/Microsoft Office Communicator pass incomplete Call Information back to Calisto in some cases
