Plivo Voice API is a powerful tool that enables developers to integrate voice calling capabilities into their applications. It is widely used for creating, receiving, and managing calls programmatically. The API is designed to handle a variety of communication needs, from simple call forwarding to complex IVR systems.
One common issue developers encounter is when a call does not ring. This can be frustrating, especially when the application is expected to handle calls seamlessly. The symptom is straightforward: the call is initiated, but the recipient's phone does not ring.
The primary cause of this issue is often incorrect call parameters or network issues. Incorrect parameters might include wrong phone numbers, misconfigured SIP endpoints, or incorrect API credentials. Network issues could involve poor connectivity or firewall restrictions blocking the call.
Ensure that the phone numbers are in the correct format and that the API credentials are valid. Double-check the configuration of SIP endpoints if used.
Verify that there are no network restrictions, such as firewalls, that might be blocking the call. Ensure that the network connection is stable and has sufficient bandwidth.
Follow these steps to resolve the issue:
By carefully verifying call parameters and ensuring network connectivity, most issues with calls not ringing can be resolved. Utilizing Plivo's documentation and support resources can further aid in troubleshooting and resolving such issues effectively.
