Set up SD-WAN Network on Working Server

In a cross-region disaster recovery scenario, you can create an SD-WAN network on the Working Server and invite the Redundancy Server at a remote site to join the network. With disaster recovery in place, the Redundancy Server can replicate telephony data from Working Server and take over telephony services if the Working Server goes down.

Requirements and restrictions

Both servers in a disaster recovery pair must meet the following requirements:
Item Requirement
Product Model Yeastar P-Series Software Edition
Plan Ultimate Plan
Version Same firmware version and must be or later.
  • LAN port as the default Ethernet interface and a static IP address is required.
  • Accessible to Yeastar SD-WAN node (
External Storage Identical storage device settings and mounting points.
Item Quantity
Max. SD-WAN network that can create or join (per PBX) 1
Max. redundancy member 1


  • Contact your service provider for the Serial Number (SN) of the Redundancy Server.
  • (Optional) Set up an email server if you want to share SD-WAN networking credential or send SD-WAN networking event notifications via email (Path: System > Email > Email Server).

    For more information, see Email Server Overview.

Step 1. Create an SD-WAN network

  1. Log in to PBX web portal, go to System > SD-WAN PBX Networking.
  2. Create an SD-WAN network.

    1. Click Create Network.
    2. In the Network Name field, enter a name to help you identify the network.
    3. Click Confirm.

An SD-WAN network is created; The Working Server has automatically joined and connected to the network, with the type displayed as Headquarter.

Step 2. Add Redundancy Server to the SD-WAN network

  1. At the top-left corner, click Add.
  2. In the pop-up window, configure the following settings, then click Confirm.
    • Serial Number: Enter the SN of the Redundancy Server.
    • Type: Select Disaster Recovery Redundancy.
The Redundancy Server is added to the list and a networking code (actually the SN of the Working Server) has been generated. You need to enter the networking code on the Redundancy Server so that it can connect to the SD-WAN network. You can click to copy the code and send it to the desired recipient, or share it by email.
Note: For more information about how the Redundancy Server can join the SD-WAN network using the code, see Join SD-WAN Network on Redundancy Server.

Tip: To access the networking code after closing the window, click beside the Redundancy Server to check and share it again.

After the Redundancy Server joins the SD-WAN network, the specified contacts of both servers will receive a SD-WAN Network Joined Successfully event notification; Both servers have been assigned network IPs, which allow them to communicate with each other over the SD-WAN network.

Tip: By default, the network IPs are hidden on the list. You can click at the top-right corner to set the Network IP column to display.
