Hybrid calling enables which of the following?

• A. Cloud-only telephony
• B. On-prem calling integrated with cloud services
• C. Voicemail storage on-prem only
• D. Presence-only services

Answer: (B)

Hybrid calling means you run some call control on your own premises while linking it to cloud services so they operate as one system. This setup lets on-prem calling be integrated with cloud services, so routing, features, directory information, and even voicemail can work across both environments. It provides a practical path to gradually migrate to the cloud without tossing your on-prem investments, while still offering seamless user experience across the two realms. The other options describe scenarios that are either fully cloud-based, strictly on-prem, or focused on presence alone, none of which capture the integrated, multi-environment calling capability.
