hub or WPP20 wireless
presentation pod is broken.
Replace it.
You cannot share content.
The WPP20 wireless presentation
pod cannot connect to the video
conferencing system.
• Connect the WPP20 to the
video conferencing system to

The far site displays black screen
when you share contents.
The reason may be that the remote
device is placed in the private LAN
and its negotiated media address
in the signaling is different from
its actual public IP address. If you
share contents in this situation,
the contents will be sent to the
negotiated media address other
than the actual public IP address.
This may lead to failure.
You can configure network address
adapter to let the content send to
the actual public IP address.
Procedure:
• On your web user interface, go
to
Setting
->
Call Features

from the drop-down menu of

(117.28.251.50 or 117.28.234.45) to test your setup. If you fail to establish a call with Yealink Demo site, contact your
network administrator to check whether or not the intranet works.
