It is recommended that you forward the web management port(443/TCP) to the public network, so that the head office can remotely
manage the branch office.

Bandwidth Requirements
To ensure the performance of video conference, the recommended bandwidth for VC800 is as below:
For more information of the configurations, contact your system administrator.
The bandwidth mentioned above is based on two-way conference. Bandwidth in head office should be increased along with the growing
number of connected branch offices .
Troubleshooting
After installation and deployment, you can test the VC800 by dialing the Yealink Demo Room. If you can’t dial out successfully, please
contact your IT administrator to check the internal network configuration.
If you do not use Cloud platform and deploy your VC800
in an Intranet, you have configured port mapping on the firewall
or gateway,
but
you find that local system appears black screen and you cannot hear sound when you call Yealink Demo or other systems.
The most
likely reason is that the firewall or gateway in your environment does not support the H.323 ALG feature. In this situation, please take the
following actions so that the NAT feature on the VC800 can solve this problem.
