What must be checked to ensure a successful 3CX installation?

To ensure a successful 3CX installation, the compatibility of user devices is crucial. This involves verifying that the hardware and software used by the end users can effectively support the 3CX system. Devices such as IP phones, desktop clients, and mobile devices must meet minimum system requirements to function properly with the 3CX platform. This not only includes checking operating system versions and network settings but also ensuring that devices support the necessary protocols and codecs that 3CX utilizes. By confirming device compatibility, organizations can avoid potential issues with call quality, connectivity, and overall system functionality, leading to a smoother implementation and user experience.
