Understanding Sinch Voice API
Sinch Voice API is a powerful tool designed to facilitate voice communication in applications. It allows developers to integrate voice calling capabilities into their applications, enabling seamless communication between users. The API is widely used in various industries, including customer support, telehealth, and more, to enhance user interaction through voice calls.
Identifying the Symptom: Call Not Initiated

This can occur due to various reasons, such as missing parameters, incorrect API endpoint usage, or authentication issues. Understanding the exact cause is crucial for resolving the issue effectively.
Common Causes of Call Request Failures
