In Webex Calling, what is the function of the "network edge"?

The function of the "network edge" in Webex Calling primarily involves providing secure connectivity for remote users. This aspect is crucial as remote access to communication and collaboration tools needs to be both reliable and secure. The network edge essentially acts as the demarcation point between the internal network and external services, ensuring that remote users can connect safely without compromising the organization's cybersecurity.

This secure connectivity typically encompasses various measures such as encryption and gateway services, which mitigate risks associated with remote access. In this way, users can effectively utilize Webex Calling features, maintain call quality, and ensure the protection of sensitive data while communicating from remote locations.

The other options do not align with the specific function of the network edge. Connecting users to the internet is a broader function that involves various network infrastructure components, while handling customer inquiries and automating call responses pertain more to messaging and customer support systems rather than the function of the network edge itself.
