In terms of infrastructure, what is a key characteristic of Webex Calling?

Webex Calling's key characteristic as a fully cloud-based solution allows organizations to leverage a flexible and scalable phone system without the need for extensive on-premises hardware. This architecture enables features like easy remote access, simplified management, and seamless integration with other cloud services. By being deployed in the cloud, Webex Calling users can access their communication tools from anywhere with an internet connection, facilitating remote work and multi-site collaboration effectively.

This cloud-centric model contrasts with options that imply limitations, such as requiring substantial physical infrastructure or being confined to a local area network. Additionally, since it does not have fixed installation requirements, it allows for adaptability in deployment, which is essential for modern businesses looking for agile communication solutions.
