What action is necessary for 3CX to process and log emergency calls?

To ensure that 3CX can effectively process and log emergency calls, it is essential to configure emergency routing settings properly. This configuration involves specifying how calls to emergency numbers are handled within the system, ensuring that such calls are directed to the appropriate emergency services with the necessary caller information. Properly set up emergency routing ensures that the system meets legal and regulatory requirements for emergency call handling, which is crucial for timely and accurate responses during emergencies.

By focusing on this configuration, 3CX can ensure that emergency calls are not only routed correctly but also that relevant data related to these calls is logged for future reference and compliance with safety protocols. The other choices, while potentially important in the overall system setup, do not directly address the specific requirements for processing and logging emergency calls.
