Download 3CX Phone System 12.5 Update (Windows)

We have just released an important Service Pack for 3CX Phone System 12.5 which will be required to reactivate 3CX upon your next system reboot. The new Mac and Windows clients have been included as well as a critical update to the license key activation module.

Because of Google’s decision to suspend SSL SHA1 certificates we have had to upgrade the 3CX licensing server to SHA2. This requires an update in the license key module in order to reactivate 3CX Phone System. Although this is only rarely required we strongly recommend that you have the system current and ready for reactivation.

Please ensure the key has valid maintenance and that valid end-user details we’re provided, as this is required to unlock the first years free maintenance.
