Create a SIP Extension

This topic describes how to create a SIP extension and configure relevant settings.


  1. Log in to PBX web portal, go to Extension and Trunk > Extension, click Add and select Add.
  2. In the User Information section, configure user information as follows:
    • First Name: Enter the user's first name.
    • Last Name: Enter the user's last name.
    • Email Address: Enter the user's email address. The user can log in to PBX web portal and Linkus clients, receive voicemail messages and PBX notifications via the email address.
      Note: An email address is exclusive to a user.
    • Mobile Number: Enter the user's mobile number. The user can receive calls or PBX notifications on this mobile number.
    • User Password: Enter a user password. The user can use the password to log in to Linkus clients.
      Note: The password is randomly generated by default. To change user password, a minimum of 10 characters with number, upper case, and lower case are required.
    • User Role: Assign a role to the user to determine whether the user can manage specific PBX features.
      The default value is None, which means that the user can not manage specific PBX features.
      Note: The system has default user roles with pre-configured permissions. You can also Create a User Role.
    • Organization: Select one or more organizations to which the extension belongs.
      Note: This option is available only when you enable the Organization Management feature.
    • Job Title: Enter a job title for the user, which will be displayed on Linkus clients.
  3. In the Extension Information section, configure extension information as follows:
    • Extension Number: Enter an extension number.
    • Caller ID: Enter a caller ID number. The caller ID will be displayed on the callee's device.
    • Registration Name: Enter a name that is used to register the SIP extension. The default registration name is randomly generated.
    • Registration Password: Enter a password that is used to register the SIP extension. The default registration password is randomly generated.
      Note: For security reasons, we recommend that you set a strong password.
    • IP Phone Concurrent Registrations: Select a value from the drop-down list.

      This option defines how many SIP endpoints are allowed to register with the extension.

      • The maximum number of concurrent registration is 3.
      • Concurrent Registration setting only limits the registration number of non-Linkus SIP endpoints. The registration number of Linkus clients is not counted.
  4. Optional: Click other tabs to configure other settings according to your needs.
  5. Click Save and Apply.


The SIP extension is created.
