PBX Improvements


  • Paging is no longer limited to 20 extensions
  • Authentication can now be set to paging in order to avoid unauthorized access
  • Multicast paging can now be configured directly in the Paging & Intercom dialogue. This is useful when many devices should be used for paging while using minimal resources.
  • NOTE: for multicast to work properly, the phones and PBX should be on the same network (this can’t be used on MT Manager tenants, for example).

IP Phone Provisioning

  • It is now possible to export, import, and duplicate templates in Endpoint Manager.
  • Export – saves the changes from the default template to a file that can be imported to another CompletePBX system.
  • NOTE: the exported file is not meant to be changed manually. Make all changes in the original template before exporting.
  • Duplicate – creates an identical template on the same machine.
  • Import – creates a new template based on the imported file.  
  • NOTE:  when creating the new template it has to be assigned a unique name on that system.
  • Endpoint Manager now supports Yealink DECT base stations:
    • W70B
    • W80
  • Added provisioning in additional Yealink phones:
    • T31W
    • T34W
    • T44W
    • T44U

Additional PBX Improvements

  • It is now possible to dial a phone number to off-hook an analog line (FXO). The caller hears the dial tone signal from the PSTN and then dials the rest of the number directly to the PSTN. A similar behavior can be also configured for the ISDN lines (BRI and PRI).


  • CompletePBX virtual machine based on Debian 12 is now available;
  • CompletePBX tenants based on Debian 12 are now available.
