What is an implication of a 3CX server lacking internet access?

When a 3CX server lacks internet access, it has several significant implications for its functionality. First, the server will not be able to access external resources necessary for various features, which can lead to limited call functionalities. This includes not being able to make or receive calls through PSTN providers or SIP trunks that require internet connectivity.

Second, while internal calls between extensions might still function without internet access, various features that rely on cloud services or external databases may not work as intended. Therefore, while there may be some ability to communicate internally, it does not negate the overall limitations imposed on the system.

Lastly, the inability to access the internet means that the server cannot connect to the 3CX update servers. This hinders the ability to download software updates that are crucial for security, performance enhancements, and the introduction of new features.

In summary, lacking internet access not only restricts call functionalities but also impacts internal operations and software updates, bringing forth a comprehensive limitation in the server's overall capabilities.
