The Click To Dial API can be applied to various scenarios:

• Delivery Scenarios: Express Delivery, Takeaway Delivery: When a courier dispatches a shipment, they can establish a call with the user by Click To Dial API, but neither knows the other’s real number, protecting the number privacy of both parties in order to avoid information leakage.
• Counselling Services: Psychological, legal, health Counselling: With the Click To Dial capability, you can hide the number information of both sides of the call to protect the user’s privacy and reduce the user’s psychological burden, and the voice quality is greatly improved, so the consultation effect is more significant.

The Click To Dial API provides developers and service providers with:

• Number Privacy: Both parties can communicate without exposing their real phone numbers, reducing the risk of unwanted contact and personal-information leakage.
• Operator-managed Calling: Unlike generic VoIP services, the operator establishes and manages both call legs using telephone-number endpoints.
• Broad Reachability: The parties do not need to use the same application or maintain a common VoIP session; they can be reached through their telephone numbers.
• Carrier-grade Voice: Calls benefit from operator-managed voice connectivity, quality and reachability.
• Simple Application Integration: A call can be initiated from a web page, mobile application or enterprise workflow through a standardized API.
• Standardized Call Notifications: Applications can track call states such as ringing, answered and disconnected through CloudEvents-based notifications.
