Updating Firmware for Polycom VVX Phones


In general we do not support or configure phones we do not supply. This is mostly because our security requirements require very specific firmware and hardware models. The process for updating generic, off-the-shelf phones takes some time and technical knowledge and doing this remotely is not possible. It can only be done locally.  For more details, please see our support article about this issue here

Can we use our current deskphones?

This information is presented only to assist you. Unfortunately we cannot assume any responsibility or liability for any upgrades or changes you make to your device.  We strongly encourage you to consult the company you bought the phone from for any other advice or assistance regarding the upgrade.
