How to Configure Fanvil A710 SBC

Fanvil A710 SBC

Important

  • You must deploy it on the same LAN as your IP phones, using the port labelled “WAN”.
  • Provisioning must be done via RPS or by entering the URL manually, similar to router phones.
  • This device itself cannot make calls, it only acts as a router phone for your local phones.
  • It’s recommended to assign a static IP to the device or use DHCP reservation if available.
  • The device needs to be assigned to a user, it cannot be configured independently like a 3CX SBC.

About the Fanvil A710 SBC

The A710 is a standalone device that can easily be deployed like a router phone, serving as a secure bridge between the 3CX Cloud PBX and local IP phones. With support for PoE and up to 100 endpoints and 50 concurrent calls, the A710 is widely suitable for scenarios such as remote work, distributed environments, and chain retail stores, delivering reliable and stable voice communication. Costs start in the region of $115.

Step 1: Factory Reset the Fanvil A710 SBC

  • Plug your device in via the WAN port.
  • With the base already powered up, hold the button until all 3 lights start flashing simultaneously.
  • The device will now reboot back into a factory reset state.

Step 2: Upgrade your Fanvil A710 SBC to the Required Firmware

Ensure that your device is on the latest firmware from here. Note: the minimum required version is v0.0.14 or higher. Future upgrades can be deployed via the 3CX Admin Console > Phones page similar to normal IP phones.

To upgrade the base manually:

  1. Log into your base IP address using default credentials admin/admin
  2. Go to System > Upgrade > Software Upgrade
  3. Click “Select” to choose your firmware file
  4. Click “Upload” to begin the upgrade process

Step 3: Add The Device to the Extension

From the admin console in your web client:

  1. Go to “Users” and select a user to deploy the device under.
    Note: You can make a separate user for this purpose, or use an existing user.
  2. Click on the “IP Phone” tab. Click “Configure a phone” to add a phone.
  3. Now select your model from the dropdown menu.
  4. Enter the device’s MAC address without dashes or colons, and click “Add phone”.

Step 4: Provision as Router

  1. Select  “Connect directly (IP Phone will be a router phone itself)”.
    Note: The other options are not applicable for this model.
  2. Click “Add Phone” to save the phone configuration for this extension.

Step 5: Connect the Device

3CX will now create the configuration information for the device and make it available at the provisioning URL. Connect your device via the WAN port so it can fetch the configuration and provision itself.

You have the following options:

  1. RPS - Connect the device to the network within 14 days. If it is already connected, factory reset it. The device will restart and configure itself automatically.
  2. Alternatively you can login to the device’s web UI and enter the URL manually.
