What is required for an organization to start using Webex Calling?

To begin using Webex Calling, an organization needs a Webex Calling subscription and internet connectivity. This is essential because Webex Calling is a cloud-based solution that operates over the internet, allowing users to make and receive calls, manage voicemail, and utilize other advanced calling features without relying on on-premises hardware.

The subscription provides the necessary licenses and access to all of Webex Calling's functionalities. Without this, users would not be able to utilize the service at all. Furthermore, reliable internet connectivity is crucial for ensuring quality calls and seamless integration with other Webex functionalities, making it an integral part of setting up Webex Calling.

The requirement of a dedicated on-premises server, only having a valid email address, or possessing an existing PBX system is not necessary for Webex Calling. This service is designed to eliminate the dependence on physical hardware in the workplace, allowing organizations to leverage the flexibility and scalability that cloud solutions offer.
