3CX Licence Changes
Last Updated: 3rd November 2025
4SC Hosting Changes
Critical decisions were made in early 2025 to allow a smooth transition for all parties affected and at the same time allowed us to focus our marketing, development and support resources on mid size & larger installs and on customers who require professional telephony solutions.
Here’s what’s new
•Alerts: There will be no further follow up alerts on a per instance basis for 4SC Hosting.
•Specific Hosting Support: You can no longer request specific hosting support for your 4SC instance.
•Release Candidates: Automatically installed on 4SC Hosted licenses. This means that during the release candidate period you cannot move out of 3CX Hosting. Once the particular update is released, however, you will be able to move out of 3CX Hosting.
3CX Enterprise AI Edition: Pricing Update & New Features
Last Updated: 28th October 2025
Extension Fair Use Policy
3CX licenses are based on simultaneous calls (SC), not per-user fees. Most users follow fair usage, but about 15% exceed the recommended extension limits.
To keep pricing fair:
•Only those exceeding limits will need to upgrade their license.
•Enforcement starts no earlier than April 1, 2026.
•Refunds may be considered for multi-year licenses if criteria aren’t met.
This gives ample time to adjust or explore other solutions.
| Simultaneous Calls (SC) | Max Extensions Allowed | Approx. Ratio (Extensions per SC) |
| 8 SC | 40 | 5.0x |
| 16 SC | 80 | 5.0x |
| 24 SC | 132 | 5.5x |
| 32 SC | 176 | 5.5x |
| 48 SC | 288 | 6.0x |
| 64 SC | 384 | 6.0x |
| 96 SC | 576 | 6.0x |
| 128 SC | 768 | 6.0x |
| 192 SC | 1,152 | 6.0x |
| 256 SC | 1,536 | 6.0x |
| 512 SC | 3,072 | 6.0x |
| 1,024 SC | 6,144 | 6.0x |

Data Deletion after Expiry
When your 3CX Subscription expires, your data will eventually be deleted. More specifically:
•5 days after expiry if your system is “Hosted by 3CX”:
‣Hosting services will be deleted
‣Renewal after this time means that you will have to redeploy to a new (empty) instance
‣You can only recover your configuration if you have retained your own backup
•30 days after expiry:
‣The license key will be deleted and will not be recoverable
‣The system’s FQDN will be deleted and will not be recoverable
Last Updated: 16th June 2025
When a licence key has expired, 3CX will retain it for 30 days.
After 30 days 3CX will delete it.
You will be notified on all 3 emails that are sent to partners, 30, 15 and 1 day before expiry.
After 30 days if you wish to get the system back, they will have to start from scratch.

4SC Enterprise – End of Life
No new 4SC Enterprise licences are available to buy
Any existing 4SC Enterprise licence keys due for renewal will either be renewed as a 4SC Professional or can be upgraded to an 8SC Enterprise.
22nd May 2025
•No licence keys will be downgraded to either 4SC or 8SC
•No licence keys hosted by 3CX, regardless of size, will be downgraded.
•No licence keys will be downgraded if the number of users / extensions exceeds 5 x the licence size. E.g. 16SC X 5 = no more than 80 extensions.
•Any issues arising from licence key downgrades will be charged at GBP / Euro / USD 250.00 per hour to investigate.
29th April 2025
You cannot use an inactivated commercial license to replace an active license key. However, inactivated commercial keys can be used to replace a trial license. Simply put, only trial keys are replaceable.
28th April 2025
3CX Trial keys are now 8SC Professional keys rather than 4SC Professional. They can still be upgraded to Proof of concept keys (Minimum 16SC). Trial keys are now only valid for 30 days. Existing keys are not affected by this change.
4SC keys can no longer be hosted by 3CX. Existing 4SC keys hosted by 3CX can be renewed in the usual way and not affected by this change. However, if an existing 4SC key hosted by 3CX expires, this key will need to be upgraded to 8SC to recover the hosting.
