What is the primary role of the IOS Gateway in Webex Calling?

The primary role of the IOS Gateway in Webex Calling is to connect time-division multiplexing (TDM) phones to Webex Calling services. This function is vital as it allows organizations that utilize legacy TDM infrastructure to transition smoothly to a cloud-based calling solution. By integrating TDM phones with modern calling services, the IOS Gateway enables businesses to retain their existing hardware while leveraging the benefits of cloud technology. This connection facilitates communication and ensures that users can still utilize familiar devices until they are ready to fully upgrade their systems.

This role is particularly important in environments where organizations may still rely on older TDM systems and are looking for a way to integrate them into a more modern framework without having to replace all their equipment immediately. The IOS Gateway bridges the gap between traditional telephony and modern cloud services, providing flexibility for businesses undergoing technological transitions.
