Network Deployment
To ensure that the VC120 works correctly, please configure it according to the conference role
that it plays. If it is in the head office, please make sure that it can be reached from the public
network. If it is in a branch office, please use an intelligent firewall to deploy it, or just follow the
same steps as for the head office
Head Office
At least one static public IP address is required in the head office to allow branch offices to
connect. The recommended endpoint configurations are as follows :
. To deploy the VC120 on a public network, you need to assign a static public IP address to the
VC120.
. To deploy the VC120 in an Intranet, you must assign a static private IP address behind the
firewall to the VC120. In the meantime, do port mapping on the firewall for VC120.
Configure a Static IP
Firstly, configure a static IP for the VC120
For example: you can use the remote control to configure the IP 10.3.20.12 to your VC120.
.
Menu->Advanced (Admin Password:0000)->LAN Configuration
. Turn off the 【DHCP】
.
Enter the IP address, subnet mask, gateway and DNS information in corresponding fields.

Branch Office
If you are in a branch office, following two options are suggested:
Option1: Deploy the VC120 following the same steps as for the head office. In this way, both inbound
and outbound calls are available.
Option2: Deploy the VC120 using an intelligent firewall, which means that plug and play is possible
without any further firewall configuration, but only outbound calls are available.
Please note that when the VC120 is deployed with an intelligent firewall, you have to open ports (as shown
below) permission if they are restricted

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 best video conference performance , the recommended bandwidth for VC120 is as
below:
For more information on configurations, contact your system administrator.
The bandwidth mentioned above is based on a two-way conference. Head office bandwidth should be
increased in line with the growing number of connected branch offices.

Troubleshooting
After installation and deployment, you can test the VC120 by dialing the 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. Using the configuration method explained in "Head Office"
chapter on page 7, you find that you can call B in branch office or Yealink Demo, but that they
cannot call you. The most likely reason is that the firewall or gateway in the environment does
not support the H.323 ALG feature. In this situation, please take the following actions so that the

NAT feature on the VC120 can solve this problem. (Carry out each step via the remote control)
. Menu->Advanced(Admin Password:0000)->NAT/Firewall
. Select 【Auto】from the 【Type】pull-down list, the endpoint will obtain public IP address
automatically.
. If the endpoint 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.
