What configurations should be considered when deploying 3CX?

When deploying 3CX, it is crucial to consider network bandwidth and firewall settings. Network bandwidth is essential because it ensures that there is enough capacity for VoIP calls to maintain clear and uninterrupted communication. Insufficient bandwidth can lead to call quality issues, such as choppy audio or dropped calls.

Firewall settings are equally important as they control the traffic that can access the 3CX system. Proper configuration of the firewall is necessary to allow VoIP traffic to pass through while keeping the system secure from unauthorized access. Specific ports must be opened to ensure that both voice and signaling traffic can flow smoothly between the 3CX server and the clients.

This option addresses the comprehensive needs of a VoIP deployment, taking into account both the performance of the network and the security of the communications. The other options do not fully encompass the necessary configurations for a successful 3CX deployment, focusing only on isolated aspects that may not provide a complete picture of the deployment requirements.
