Vonage Voice Call Not Answered

The call was not answered by the recipient.

Understanding Vonage Voice API

Vonage Voice API is a powerful tool designed to facilitate voice communication through applications. It allows developers to integrate voice calling capabilities into their applications, enabling seamless communication between users. The API supports a wide range of functionalities, including making and receiving calls, call recording, and more.

Symptom: Call Not Answered

One common issue developers encounter when using the Vonage Voice API is that calls are not answered by the recipient. This can be frustrating, especially when the call is crucial for business operations or customer service.

What You Observe

When this issue occurs, you will notice that the call is initiated, but the recipient does not pick up. The call may eventually time out or be marked as unanswered in your application's logs.

Details About the Issue

The primary reason for a call not being answered is that the recipient is unavailable or the number dialed is incorrect. This can happen due to various reasons, such as the recipient being busy, the phone being turned off, or network issues.

Common Error Codes

In some cases, you may receive specific error codes from the API indicating the call status. For example, a status code of NO_ANSWER may be returned, signaling that the call was not picked up.

Steps to Fix the Issue

To resolve the issue of calls not being answered, follow these steps:

1. Verify the Recipient's Availability

Ensure that the recipient is available to take the call. You can send a message or use an alternative communication method to confirm their availability.

2. Check the Dialed Number

Double-check the phone number you are dialing. Ensure that it is correct and formatted according to international dialing standards. Refer to the Vonage documentation for more details on number formatting.

3. Review Network Connectivity

Ensure that both your application and the recipient's device have stable network connections. Network issues can prevent calls from being successfully connected.

4. Implement Retry Logic

If the call is not answered, consider implementing a retry mechanism. You can schedule the call to be retried after a certain period, increasing the chances of it being answered.
