3CX Pricing

3CX is based on simultaneous calls made within your company along with the Standard and Pro editions. 
Pricing shown is for the software only and excludes installation and commissioning.

Simultaneous Calls
Licensing is based on the number of simultaneous calls that your company requires, including both external and internal calls. Each 3CX Phone System allows you to create an UNLIMITED number of extensions. 

To arrive at the correct number of simultaneous calls that you will need you must usually take the projected number of extensions and divide by two to four times depending on how much your organisation uses the phone.

Usually, 1 sim. call per 3-4 extensions is required, i.e. a company with 50 extensions would need a 16 sim. call license.
