How is "Security" managed in 3CX?

In 3CX, security is primarily managed through the implementation of secure SIP and IP blacklisting. Secure SIP, also known as TLS (Transport Layer Security), encrypts the signaling data, which protects it from eavesdropping and man-in-the-middle attacks. By using secure SIP, 3CX ensures that sensitive voice communications and other signaling information are transmitted securely over the network.

IP blacklisting is another crucial aspect of security management in 3CX. It allows administrators to block traffic from specific IP addresses or ranges that are known to pose a threat, such as those associated with malicious activity or intrusion attempts. This proactive approach helps protect the system from unauthorized access and potential security breaches.

While other methods like user training programs, disabling SIP features, and limiting call access can contribute to overall system safety, they do not provide the robust level of security that secure SIP and IP blacklisting offer. These latter options focus directly on safeguarding the VoIP infrastructure, making them fundamental to 3CX's security strategy.
