Network Deployment
Yealink Cloud Deployment
VC120 supports two network deployment methods: Yealink Cloud deployment and traditional deployment. Choose the
desired deployment method according to your needs.
. Select Menu->Advanced (Admin Password:0000)->Yealink Cloud
.
Select desired sign-in method from the pull-down list of Login Type
1）You can sign into the 9-digit enterprise Cloud account using PIN code or username/password (enterprise Cloud
account can be managed via Yealink VC Cloud Management Service)
2）You can also use 7-digit build-in Cloud number (build-in Cloud number cannot be managed via Yealink VC Cloud
Management Service)
With Yealink VC Cloud management service, organizations can communicate just using a Cloud account. Both the head
office and the branch offices can use this deployment method. Get Cloud account information from your Cloud enterprise
administrator, and do the following to sign into your VC120 via remote control:

Head Office
Configure a Static IP
The following introduces how to configure a static IP address for the VC120.
Select Menu->Advanced (Admin Password:0000)->LAN Configuration
9
Select IPv4 from the IP Mode pull-down list
Select IPv4
Option2: To deploy the VC120 in an Intranet (behind the firewall), you must assign a static private IP address to the
VC120. In the meantime, do port mapping on the firewall for VC120.
Traditional Deployment
Option1: To deploy the VC120 on a public network, at least one static public IP address is required, you need to assign
a static public IP address to the VC120.
Turn off the DHCP
.
If you do not use Cloud accounts, you can choose traditional deployment method to deploy your VC120, and dial IP
addresses of other devices to make a call.
In order to ensure that the VC120 can work properly, please configure it according to the role it plays in the meeting.
If it is in the head office, please make sure that it is reachable from public network. If it is in branch office, please use
intelligent firewall traversal to deploy it or just follow the same steps as for the head office.
.
.
.
For example: use the remote control to configure a static IPv4 address to your VC120.
If you deploy VC120 in the head office, at least one static public IP address is required in the head office to allow branch
offices to connect. Do one of the following to deploy VC120:

Configure Port Mapping
If the VC120 is deployed in an Intranet, and you want to solve the interconnection problem by port mapping, you must
forward the following ports to the public network on the firewall.
. Press Save to save the configuration,
. The screen prompts Reboot now
. Press OK to reboot the system.

.

Branch Office
If you delpoy VC120 in the branch office, do one of the following to deploy it:
Option1: Deploy the VC120 following the same steps as for the head office. In this way, both inbound and outbound calls
will be 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 9,
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.
