Version 11 is no longer available for download. To download the updated version click here.
In an effort to consolidate our users onto fewer and more recent versions, we have decided to provide all 3CX Phone System v10 and older users with a FREE upgrade to 3CX Phone System v11. V11 offers many new features and security improvements compared to version 10, 9 and 8. It is important to note that recent SSL changes (revoking of SHA-1 certificates by Google) will force us to update our licensing server imminently, and in turn to reactivate, end users will need to use a later version. Re-activation will only be required if you need to reinstall or if a major change takes place in your network.
To install the free upgrade please follow the steps below:
- Backup your current version and download 3CX Phone System 11.
- Install and restore from backup.
- The Administrator Manual for 3CX Phone System v11 can be found here.
- Your licence key has been automatically updated to v11.
Please note we will not be able to support v11 users. V11 is end of life. Ideally you would buy an upgrade to version 12.5 but if you can not afford that, v11 is a good option. Feel free to comment below (with name and email) or fill in the form.
