3CX is priced as an annual license/subscription fee based on the number of simultaneous (SIM) calls required.  As an industry average, 3 extensions require one call path, i.e.- a company with 50 extensions would need at least 16 simultaneous calls.  Licenses can be upgraded to the next highest sim. call package by simply paying the difference for the remaining period.

License pricing includes one year of maintenance: including but not limited to free software updates, security enhancements, smartphone clients, tested phone firmware updates, and new versions (ex- v14 to v15).

3CX software is delivered electronically and is activated by means of a license key.  Pricing does not include taxes.
