Configure Network for Remote SIP Access by a Yeastar FQDN

With a Yeastar FQDN, you can quickly establish a secure tunnel for remote registration of IP phones, alike SIP endpoints, and account trunks, without port forwarding. This topic introduces how to configure network for remote SIP access via FQDN.


You have subscribed Yeastar P-Series Enterprise Plan or Ultimate Plan.


  1. Log in to PBX web portal, go to System > Network > Yeastar FQDN.
  2. Turn on Yeastar FQDN.
  3. Set up the FQDN domain name.
    1. In the Fully Qualified Domain Name (FQDN) field, select a domain name, then enter a hostname.

      For example, select domain name and enter hostname yeastardocs, you will get an FQDN

      Note: Think twice before you enter the hostname. The FQDN cannot be changed after you save the configurations.

    2. Click Save.
  4. Enable remote SIP access feature and configure usage permission.
    Note: By default, all accounts are NOT allowed to use the remote SIP access feature. You need to grant the usage permission to desired accounts.
    1. In the Features section, click beside the SIP Access.
    2. In the pop-up window, complete the following settings according to your need.

      • Name: Display the remote access feature name, and cannot be edited.
      • Status: Select Enabled.
      • Remote Access Service Port: The remote access ports will be assigned by Remote Access Service automatically.
      • Access Type: Define the account access restriction type for the feature.
        • Allowed Account: Only the selected accounts can get access to the service.
        • Restricted Account: All accounts except for the selected accounts can get access to the service.
      • Select Account: Select the desired accounts that can or can not use the remote access feature.
      • Organization: Select the desired organization(s) that can or can not use the remote access feature.
        • This setting is available only when the Organization Management feature is enabled.
        • By default, when you select an organization, its associated sub-organizations are selected. Be careful when selecting organizations.
      • Enable IP Restriction: Optional. Select the checkbox of the option, and add at least one permitted IP address and subnet mask.

        If you configure this option, only the permitted IP address(es) can use the remote access feature.

    3. Click Confirm.
  5. Click Save and Apply.


  • The Remote Access Service automatically assigns ports for remote SIP access.

  • You can implement remote SIP registration via FQDN, including the registration of remote SIP extension and SIP account trunk.
    Important: The remote SIP access feature via FQDN does NOT support the remote registration of SIP peer trunk.
