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
of firmware/software I am
using?
• Go in Menu> Settings> About Calisto
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
