@Matt I'm sorry to hear you're experiencing issues with connecting your SIP endpoints. Let's try to troubleshoot this step by step: 1. **Check Network Configuration**: Ensure that your network allows SIP traffic and that the necessary ports are open. SIP typically uses UDP port 5060. 2. **Verify SIP Endpoint Configuration**: Double-check the configuration of your SIP endpoints. Make sure that the credentials, domain, and server settings are correct. 3. **Inspect Assistant Configuration**: Confirm that the assistants are correctly configured to handle calls from the SIP endpoints. 4. **Review Bandwidth.com Settings**: If you're forwarding a number from Bandwidth.com, ensure that the forwarding settings are correct and that the number is properly linked to your SIP endpoint. 5. **Examine Logs**: Look at the logs for any error messages. This can provide clues as to what might be going wrong. 6. **SIP REFER Messages**: If the calls are being transferred but not connecting, ensure that your Vici system can handle SIP REFER messages. 7. **API Attributes**: If you're using the

attribute in the API and encountering issues, try omitting it or setting it to null or an empty string. If you've gone through these steps and the issue persists, please provide more details or any error messages you're seeing so we can assist you further. If you're seeing specific error messages in the logs, that information would be particularly helpful.
