Plivo Voice Call not connecting

Network issues or incorrect call parameters.

Understanding Plivo Voice API

Plivo Voice API is a powerful tool that enables developers to integrate voice calling capabilities into their applications. It is widely used for creating seamless communication experiences, allowing applications to make, receive, and control calls programmatically. This API is part of the broader category of Voice/Calls Communication API providers, offering robust features for voice communication.

Identifying the Symptom: Call Not Connecting

One common issue developers encounter when using Plivo Voice API is the 'Call not connecting' problem. This symptom is observed when an application attempts to initiate a call, but the call fails to establish a connection. Users might notice that the call does not ring or connect to the intended recipient.

Exploring the Issue: Network or Parameter Problems

The root cause of the 'Call not connecting' issue often lies in network connectivity problems or incorrect call parameters. Network issues can prevent the call from reaching the Plivo servers, while incorrect parameters can cause the API to reject the call request. It's crucial to diagnose the exact cause to apply the correct resolution.

Network Connectivity

Ensure that your application has a stable internet connection. Network disruptions can lead to failed API requests. Check your network settings and firewall configurations to ensure that they allow outbound connections to Plivo's servers.

Call Parameters

Verify that all call parameters, such as the destination number and caller ID, are correctly formatted and valid. Incorrect parameters can lead to API errors. Refer to the Plivo API documentation for the correct parameter formats.

Steps to Resolve the Issue

Follow these steps to troubleshoot and resolve the 'Call not connecting' issue:

Step 1: Check Network Connectivity

  • Ensure your server or application has a stable internet connection.
  • Use tools like ping or traceroute to test connectivity to Plivo's servers.
  • Review firewall settings to allow traffic on the necessary ports.

Step 2: Validate Call Parameters

  • Double-check the destination number format. It should include the country code.
  • Ensure the caller ID is a valid number registered with Plivo.
  • Refer to the Plivo Call API parameters for detailed information.

Step 3: Review API Logs

  • Access your Plivo account dashboard and review the API logs for any error messages.
  • Look for specific error codes or messages that can provide more insight into the issue.

Conclusion

By ensuring network connectivity and verifying call parameters, you can effectively resolve the 'Call not connecting' issue in Plivo Voice API. For further assistance, consider reaching out to Plivo Support or consulting the Plivo Documentation for more detailed guidance.
