    Hello,
    I am following this tutorial: https://www.3cx.com/blog/docs/3cxphone-for-windows-api/
    And I face problem that 'OnCallStatusChanged' is never called, like these two guys:
    https://www.3cx.com/community/threads/oncallstatuschanged-never-fires.41704/
    and
    https://www.3cx.com/community/threads/phone-api-oncallstatuschanged-not-working-as-it-used-to.45326/

    I notice that in the tutorial, the author mentioned "3CX PROFESSIONAL License Key".
    Is that a MUST HAVE pre-condition to develop with that API?
    It is nonsense for me because if I am not sure that we can integrate 3CX with our CRM system or not, it is difficult for my company to decide to buy a PRO license.

    Thank you!

    Hi ThanhLoyal

    Yes, 3CX PRO is a "Must have" when you Program with the API.
