Twilio Voice Error 13236

Invalid 'SipAuthUsername' or 'SipAuthPassword'.

Understanding Twilio Voice

Twilio Voice is a powerful API that allows developers to integrate voice communication capabilities into their applications. It is widely used for making and receiving phone calls, managing call flows, and integrating with other communication channels. The API provides a robust platform for building voice applications that can scale with your business needs.

Identifying the Symptom: Error 13236

When working with Twilio Voice, you might encounter Error 13236. This error typically manifests when there is an issue with authentication credentials, specifically related to SIP (Session Initiation Protocol) authentication. The error message indicates a problem with either the 'SipAuthUsername' or 'SipAuthPassword'.

Exploring the Issue: Invalid Credentials

Error 13236 is triggered when the SIP authentication credentials provided are incorrect. This can happen if the username or password is mistyped, or if there have been changes in the credentials that have not been updated in your application. Ensuring that these credentials are accurate is crucial for establishing a successful connection.

Common Causes

  • Typographical errors in the 'SipAuthUsername' or 'SipAuthPassword'.
  • Credentials have been changed but not updated in the application.
  • Using outdated or incorrect credentials.

Steps to Resolve Error 13236

To resolve this error, follow these steps to verify and update your SIP authentication credentials:

Step 1: Verify Credentials

First, double-check the 'SipAuthUsername' and 'SipAuthPassword' in your application configuration. Ensure there are no typographical errors. You can find these credentials in your Twilio Console under the SIP Domains section.

Step 2: Update Credentials

If you have recently changed your SIP credentials, make sure to update them in your application. Log in to your Twilio account, navigate to the SIP Domains page, and verify the current credentials.

Step 3: Test the Connection

After updating the credentials, test the connection to ensure that the error is resolved. You can use tools like Twilio's SIP Interface to simulate calls and verify that the authentication is successful.

Conclusion

By carefully verifying and updating your SIP authentication credentials, you can resolve Error 13236 and ensure seamless voice communication through Twilio Voice. For further assistance, refer to the Twilio Voice Documentation for more detailed guidance.
