Option1
: Deploy the endpoint following the same steps as for the head office. In this way,
both inbound and outbound calls are available.
Option2
: Deploy the endpoint using intelligent traversal. You only need to assign a private IP
address to your endpoint. Make sure this private IP address can access the public network.
Only outbound calls are available when using this method.
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 the head office can remotely manage the branch office.
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, you have configured port
mapping on the firewall or gateway, but you find that local endpoint appears black screen and you
cannot hear 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
Auto
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.
