IMPORTANT This guide has been tested with firmware versions 6.5.15 & 7.1.30. Be aware that different firmware revisions may have different web interface formats and functionality. See compatibility list for latest phone firmware revisions that we have tested with 3CX Phone System.

This feature is only available in the commercial edition of 3CX Phone System.

After you have created the extension in 3CX Phone System, and entered the MAC address of the phone as well as specified the model, you need to configure the phone to retrieve the configuration from the 3CX Phone System HTTP server:

  1. Switch on the phone. During the boot up process the IP Address of the phone set will be displayed on the screen. Keep a note of the IP Address.
  2. Assuming that the phone set’s IP is 10.172.0.104, use a web browser to access the phone set’s configuration, using this URL: http://10.172.0.104
  3. From the left-hand side menu, in the “Setup” section click on Advanced.



  4. If it is a new phone set, ignore step 5 and proceed to step 6.   
  5. If the phone was used before, click the Reset button at the bottom of the page, and click the Yes button to confirm a factory defaults reset.  
  6. In the “Update” section, from the Update policy drop down menu, select “Update Automatically”, so next time the phone set is rebooted, it retrieves the configuration from the 3CX Phone System http server.  
  7. In the Setting URL input field, input as follows: http://10.172.0.116:5481/provisioning/cfg{mac}. Where the IP must be the IP of the 3CX Phone System machine. The rest should remain as shown; the phone will automatically replace {mac} with its own MAC address so that it retrieves the correct configuration file after reboot.
      



  • Saving configuration and reboot the phone.
    1. Click on the Save button at the bottom of the page to save the new HTTP provisioning settings.
    2. After saving the configuration changes, click on the Reboot button at the bottom of the page to reboot the phone set and retrieve the configuration from the 3CX PBX Phone System.
