Which Webex feature enables hybrid calling with CUCM?

• A. Calling in Webex App (Hybrid)
• B. Hybrid Calling Plan
• C. CUCM Connector
• D. Webex Hybrid Gatekeeper

Answer: (A)

The concept being tested is how hybrid calling is provided between Webex and CUCM, so users can use the Webex App to place and receive calls while CUCM handles call control and PSTN routing. The best choice is Calling in Webex App (Hybrid) because it directly enables this experience: the Webex App acts as the user’s dialing client, but the actual call signaling and control occur through CUCM, delivering a seamless integration of cloud collaboration with on‑prem telephony.

In this setup, users benefit from the familiar Webex interface while still leveraging CUCM for dialing plans, features, and on‑prem routing. This typically involves the Webex cloud coordinating with CUCM via Expressway components to bridge signaling and media between the Webex environment and the on‑prem system. The other options refer to components or terms that do not specifically describe enabling the Webex App to initiate and manage calls with CUCM in hybrid mode.
