When working with Telnyx's Voice API, you might encounter the error code SIP 606 Not Acceptable. This error typically manifests when a call attempt fails, and the response indicates that the request is not acceptable for unspecified reasons.
The SIP 606 Not Acceptable error is part of the SIP (Session Initiation Protocol) response codes. It signifies that the request cannot be processed due to unspecified reasons, often related to compatibility issues between the caller and the recipient.
To address the SIP 606 error, follow these actionable steps:
Ensure that the request parameters, such as codecs and media types, are compatible with the recipient's capabilities. You can refer to the Telnyx API Documentation for detailed information on supported codecs.
Verify that your network and firewall settings allow SIP traffic. Ensure that the necessary ports are open and not blocked by any security policies. For more information, visit Telnyx Network Requirements.
Experiment with different configurations, such as changing the codec settings or adjusting the media types in your request. This can help identify compatibility issues. Use tools like Wireshark to analyze SIP traffic and diagnose problems.
