Can Webex Calling function without an internet connection?

Webex Calling is a cloud-based communication service that relies heavily on internet connectivity to function. The entire platform is designed to operate through the internet, which enables features like voice calls, video conferencing, messaging, and more. Each of these services requires data transmission to and from the Webex servers, making a stable internet connection essential for the functionality of Webex Calling. Without internet access, users would not be able to connect to the servers hosting the necessary resources and services required for calls and collaboration tools.

In contrast, options suggesting that Webex can function offline misrepresent the operational requirements of the platform. While some communication apps may have offline functionalities where basic features could work without an internet connection, Webex Calling specifically does not support this, as all its features need to connect to the cloud infrastructure. Thus, the accurate understanding is that a stable internet connection is crucial for Webex Calling to operate effectively.
