About VoIP System Updates:

Firmware updates for VoIP Systems are very complex and usually contain many bug fixes, security improvements and compatibility enhancements, because the base system must be able to connect to webcams, video conference devices and the like.

Upgrading your VoIP System firmware should be done as often as possible to keep your device up to date with new security standards, and improve the native plug and play capabilities of your device.

Although beta firmware are usually full of new and exciting features, updating to them should only be done after thoroughly reading the changelog and making sure that you still retain phone functionality. Remember to check if you can revert to a more stable version as well, in case the new update is not what you were expecting.

If you intend to apply this update, please make sure that the package is compatible with your VoIP System, hit the download button, follow the installation instructions and enjoy. Check out our website as often as possible in order to keep your device “Updated one minute ago.”
