3CX Academy Basic Certification Practice Test

3CX clients do indeed send requests for Computer Telephony Integration (CTI) to the PBX, which then relays these requests to the IP phone. This process facilitates various integrations between the phone system and the client applications, allowing features such as call control, call pop-ups, and other functionalities that enhance productivity and streamline communications.

The integration works by the PBX acting as the central point of communication, effectively managing the requests from the clients and ensuring that the IP phones have the necessary commands and information to execute those requests. This is fundamental to how 3CX operates, enabling seamless interaction between the user interface and telephony hardware.

Understanding this mechanism highlights the role of the PBX in coordinating activities between software applications and hardware devices, illustrating the importance of the PBX as a hub in the 3CX system.
