Regarding the file constraints for Digital Receptionist prompts, which statement is correct?

The correct answer emphasizes that prompts for a Digital Receptionist must be encoded properly to be accepted by the system. This is critical because digital communication systems like 3CX have specific requirements for audio file formats to ensure quality and compatibility. Proper encoding affects factors such as clarity, volume, and the overall clarity of the prompt when played back to users.

Audio files that do not meet the required encoding standards may result in distorted or inaudible prompts, which can severely impair user experience. Generally, compliant formats might include WAV files encoded with specific parameters, and the system is likely to reject any files that do not meet these standards. Meeting encoding requirements is essential for seamless integration and functionality within the 3CX system, thereby ensuring a smooth and professional interaction for callers.

The other options touch on specific aspects of file types and encoding that don't accurately reflect the overarching requirement of correct encoding to ensure acceptance and functionality of the prompts within the 3CX system.
