Troubleshooting
Connectivity Testing
After installation and deployment, you can test the endpoint by dialing the Yealink Demo Room
( 117.28.251.50 or 117.28.234.45 ). If you can’t dial out successfully, please contact your IT
administrator to check the network.
Configuring Static NAT
If you do not use Cloud platform and deploy your endpoint in an Intranet, and you have configured port
mapping on the firewall or gateway, but you find that local endpoint appears black screen and you
cannot hear any sound when you call Yealink Demo or other endpoints. The most likely reason is that
the firewall or gateway in your environment does not support the ALG feature. In this situation, please
take the following actions so that the static NAT feature on the endpoint can solve this problem.
To configure static NAT via the remote control:
1. Select More -> Network -> Wired Network (Default Admin Password:0000)-> NAT/Firewall .
2. Select Automatic from the pull-down list of Type , the endpoint will obtain public IP address
automatically.
3. If the endpoint does not obtain a public IP address automatically, select Manual Settings from the
pull-down list of Type , and then enter the public IP address in the Public IP Address field.
4. Save the change.

When you use intelligent traversal to deploy your endpoint, you have to open following ports on
your firewall if they are restricted.
It is recommended that you forward the web management port(443/TCP) to the public network,
so that you can manage the endpoint remotely.

If you deploy the endpoint in an Intranet, you must forward the following ports to the public network on
the firewall, so that your endpoint can receive a public-to-private call.
