Workflow to set up online faxing

To enable online faxing on Yeastar P-Series PBX System and allow extension users to send and receive faxes through Linkus, you need to perform the following operations.
  1. Integrate PBX with third-party fax platform(s).
  2. (Optional) Add and customize cover page(s), which will be available for extension users to use when they send faxes.
    Note: Extension users who are authorized to send faxes can also customize their own cover page(s) from Linkus Desktop or Web Client.
  3. (Optional) Customize the built-in Fax to Email template, which will be used when faxes are forwarded to mailboxes.

    When done, extension users can send and receive faxes directly from Linkus Desktop or Web Client.

Fax data auto cleanup

Yeastar P-Series PBX System logs all inbound and outbound fax activities and stores the associated fax files. By default, the system automatically deletes fax data when either of the following thresholds is reached:

  • Fax Files: The maximum storage reaches the following limit:
    • P520: 300MB
    • P550: 500MB
    • P560/P570: 1024MB
  • Fax Logs: Fax logs are retained for up to 7 days, or the total number of logs reaches 200,000.

You can adjust the maximum storage size for fax files or the preservation day for fax logs in System > Storage > Fax Data Auto Cleanup.

Note: The maximum number of fax logs is fixed and cannot be modified.
