Ring Office Phone and Mobile Phone Simultaneously

This topic describes how to achieve simultaneous ring on office phone and mobile phone.


A user may miss important calls when he or she is away from desk or on a business trip. In this case, you can enable simultaneous ring for the user. When a call reaches the user's extension number, both mobile phone and office phone with the extension number logged in will simultaneously ring.


  • You have set a mobile number for the extension.
  • At least one outbound route is ready for use.


  1. Log in to PBX web portal, go to Extension and Trunk > Extension, edit the desired extension.
  2. Click Presence tab.
  3. In the status bar, select a status to which the strategy of simultaneous ring will be applied.
  4. In the Options section, configure the following settings.
    1. Select the checkbox of Ring the Mobile Number Simultaneously.
    2. Click to configure mobile number.
    3. Optional: In the Prefix field, enter the prefix of outbound route so that PBX can successfully send calls to your phone.
      • If the Strip of outbound route is not set, you don't have to set the Prefix.
      • If the Strip of outbound route is set, you need to set the Prefix according to the Patterns of outbound route.
  5. Click Save and Apply.


If a call reaches the user's extension number when he or she is in the specified presence, both office phones and mobile phone will ring simultaneously.
