How are multi-site configurations managed in 3CX?

Multi-site configurations in 3CX are effectively managed through VPN connections between multiple 3CX systems. This approach allows seamless communication and integration between the sites while ensuring that they can operate as a unified system. By establishing VPN connections, the various installations can share resources, such as extensions, call features, and other functionalities inherent to a 3CX environment.

VPNs provide a secure method for inter-site communication, which is crucial for maintaining data integrity and privacy when transmitting voice traffic and other sensitive information between locations. This setup ensures that callers from one site can reach the extensions deployed at another without complications, as they appear to be on the same network.

The other options lack the necessary connectivity and flexibility that VPNs offer. Managing each site separately without connection would lead to fragmented operations, limiting inter-site communication and collaboration. Relying on dedicated hardware for each location could also prove costly and inefficient, as it would require individual management without the benefits of centralized control. Lastly, focusing exclusively on cloud-based solutions may not provide the same level of local control and customization that VPN connections allow, especially in scenarios where privacy and latency are concerns. Thus, utilizing VPN connections provides an effective balance of performance and security suitable for multi-site 3CX configurations.
