Step 2 – Choose your 3CX License Size

3CX licenses work on a simultaneous call basis

 3CX licences are available in 13 different sizes based on the number of simultaneous calls your business needs to make. This includes external and internal calls.

For businesses with average call volumes, an available telephone line (simultaneous call) can be shared by up to 3 people. For example, if you have 12 people, you will need a 4-simultaneous call 3CX License.

You can upgrade your license at any time by just paying the cost difference, so we recommend starting with a smaller 3CX license and then upgrading if you need to.
