Question

What firmware is recommended for 8x8 phones and analog adapters?

Applies To 

  • Phone Settings
  • Phone Firmware

Answer

The tables below list the latest certified and recommended firmware versions for devices used with 8x8. This list is actively updated as new firmware revisions are certified and released for general availability within 8x8. For a list of features available on supported devices click here.
Newer uncertified firmware may work with the 8x8 system if used, however, if the firmware has not been certified for use there may be issues that 8x8 will be unable to solve without downgrading the affected devices to an 8x8-certified firmware.
In most cases the recommended firmware is automatically pushed to a device upon activation. If an uncertified firmware was installed on a device post-activation, the easiest way to revert the firmware is to deactivate the device and re-activate it.  If mass firmware updates are desired, contact support to have them push updates to your devices after hours.
