Sinch Voice Incorrect Caller ID

The caller ID displayed is not as expected.

Understanding Sinch Voice API

Sinch Voice API is a powerful tool designed for developers to integrate voice calling capabilities into their applications. It allows for seamless voice communication, providing features such as call management, caller ID customization, and more. The API is widely used in production environments to enhance user interaction through voice calls.

Identifying the Symptom: Incorrect Caller ID

One common issue encountered by developers using the Sinch Voice API is the display of an incorrect caller ID. This symptom manifests when the caller ID shown to the call recipient does not match the expected number configured in the application settings.

What You Might Observe

When this issue occurs, the recipient of the call sees a different number than intended. This can lead to confusion and potential trust issues with end-users, as they may not recognize the number calling them.

Exploring the Root Cause

The root cause of the incorrect caller ID issue often lies in the configuration settings within the Sinch Voice API. It could be due to incorrect parameters in the API request or misconfigurations in the account settings.

Common Misconfigurations

Some common misconfigurations include:

  • Incorrectly set caller ID in the API request payload.
  • Account settings not reflecting the desired caller ID.
  • Restrictions or limitations imposed by the telecom provider.

Steps to Fix the Incorrect Caller ID Issue

To resolve the incorrect caller ID issue, follow these detailed steps:

Step 1: Verify API Request Parameters

Ensure that the caller ID is correctly specified in your API request. Check the JSON payload for the from field, which should contain the desired caller ID. For example:

{
"from": "+1234567890",
"to": "+0987654321",
"method": "call"
}

Refer to the Sinch Voice API documentation for more details on request parameters.

Step 2: Review Account Configuration

Log into your Sinch account and navigate to the voice settings. Ensure that the caller ID settings are correctly configured to reflect the number you wish to display. Check for any restrictions or limitations that might be affecting the caller ID.

Step 3: Contact Telecom Provider

If the issue persists, it might be due to restrictions imposed by the telecom provider. Contact your provider to ensure that the desired caller ID is allowed and properly configured on their end.

Conclusion

By following these steps, you should be able to resolve the incorrect caller ID issue in your Sinch Voice API implementation. Always ensure that your API requests and account settings are correctly configured to prevent such issues. For further assistance, consider reaching out to Sinch Support.
