PABX firmware Upgrades - Additional notes

  • ALWAYS click on the Update firmware version list link or button before attempting an upgrade, or checking handset firmware.
  • If a licence issue is reported, it may be as simple as clicking on the serial number under the menu on the left and requesting an updated licence.
  • Always read the help text on the Upgrades menu. This covers both upgrade and rollback procedures in case of issues.
  • If using very old or discontinued Polycom handsets, refresh the firmware list, and use “Handset firmware mode” to see whether any of the older firmware needs updating.
