What happens when an 8SC licence with over 200 extensions reaches the new 40-extension limit?

[Hassan_mfts]

We manage a customer’s 3CX system with an 8SC licence and more than 200 configured extensions. We have received a notification stating that an 8SC licence will support a maximum of 40 extensions and that the limit will be enforced from 1 October 2026.

Could someone please clarify the following?

1. What exactly will happen when the limit is enforced?
2. Will extensions above the limit be disabled or deleted?
3. Will inbound and outbound calls stop working?

We need to understand the impact so that we can advise the customer and plan the appropriate upgrade without service disruption.

1. You won't be able to create new users.
2. We don't know. Just get compliant by the deadline.
3. No.

Thank you for clarifying.

As the exact enforcement behaviour is currently unknown, could a member of the 3CX team please provide an official response?

We particularly need confirmation of whether the existing 200+ extensions will continue working after 1 October 2026, or whether calls and other services will be affected. We also need guidance on the correct licence upgrade for supporting this number of extensions without disruption.

You'll need a 48SC, or remove some users to get down to 192 and get a 32SC.

Make sure to do this before the deadline and you won't have to worry about stuff breaking.

Being last minute will definitely bite you in the arse.
