In order to ensure that the VC400/VC120 can work properly, please configure it according to the
role it plays in the conference. If it is in the head office, please make sure that it is reachable from
the public network. If it is in the branch office, please use intelligent firewall to deploy it or just
follow the same steps as in the head office
Head Office
At least one static public IP address is required in head office to allow branch offices to connect.
The recommended system configurations are as follows :
. Deploy VCS on public network, you need to assign a static public IP address to VCS.
. Deploy VCS in Intranet, you need to assign a static private IP address behind the firewall to
VCS. At the meantime, do port mapping on firewall for VC400/VC120.
Configure a Static IP
First of all, configure a static IP for the VC400/VC120
For example: you can use the remote control to configure the IP 10.2.18.74 to your VC400/VC120.
.
Menu->Advanced (Admin Password:0000)->LAN Configuration
. Turn off the 【DHCP】
.
Enter the IP Address, Subnet Mask, Gateway, DNS information in corresponding fields.

Branch Office
If you are in branch office, following two options are suggested:
Option1: Deploy the VCS following the same steps as in the head office. In this way, both inbound
and outbound calls are available.
Option2: Deploy the VCS using intelligent firewall, which means plug and play is possible without
any further firewall configuration, but only outbound call is available.
Please note that when the VCS is deployed with intelligent firewall, you have to open ports (as shown below)
permission if they are restricted

Bandwidth Requirements
To ensure the performance of video conference. The recommended bandwidth for VC400\VC120
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 .

After the installation and deployment, you can test the VC400/VC120 by dialing Yealink Demo
Room. If you can’t dial out successfully, please contact your IT administrator to check the internal
network configuration.
Assume that you are A in head office and use the configuration method introduced in "Head Ofiice"
chapter on page 7, you are able to call B in branch office or Yealink Demo, but they cannot reach
you. The most likely reason is the firewall or gateway in the environment does not support H.323

ALG feature. In this situation, please do as follows to enable NAT feature on VCS to solve this
problem. (Do following steps via the remote control)
. Menu->Advanced(Admin Password:0000)->NAT/Firewall
. Select 【Auto】from the 【Type】pull-down list, the system will obtain public IP Address
automatically.
. If the system does not obtain a public IP Address automatically, select【Manual Settings】from
the 【Type】pull-down list, and then enter the public IP address in the 【Public IP address】field.
