The provided content does not include specific IP addresses or CIDR ranges for ElevenLabs' SIP trunking setup. To integrate ElevenLabs with Twilio, you may need to ensure the following:

  1. Authentication Method: ElevenLabs supports both digest authentication and IP-based authentication. Ensure you configure the SIP trunk in the ElevenLabs Conversational AI dashboard accordingly.

  2. Firewall and ACLs: If you require IP addresses for whitelisting in Twilio's ACL, you will need to contact ElevenLabs' support team directly for a comprehensive list of signaling IPs or CIDR ranges used by ElevenLabs.

  3. Audio Requirements: Ensure that your system supports a 48kHz audio sample rate, as this is required for ElevenLabs' SIP deployment.

  4. Transport Protocols: Verify whether your setup uses TCP, UDP, or TLS for SIP signaling and configure both platforms to match.

If you still face issues or need further technical details, I recommend reaching out to ElevenLabs' support team for assistance. You can submit a ticket through their Help Center.

Setting up a SIP trunk from ElevenLabs to Twilio requires proper configuration on both platforms. Here are some key points to consider:

  1. ElevenLabs SIP Trunk Configuration:

    • The SIP server for ElevenLabs is sip.rtc.elevenlabs.io.
    • Ensure you are using the correct transport protocol and port:
      • TCP: sip:sip.rtc.elevenlabs.io:5060;transport=tcp
      • TLS: sip:sip.rtc.elevenlabs.io:5061;transport=tls
    • ElevenLabs supports both digest authentication and IP-based authentication. Choose the method that aligns with your setup.

  2. Twilio ACL (Access Control List):

    • If you need to add ElevenLabs' IP addresses to Twilio's ACL, you may need to resolve the IP address of sip.rtc.elevenlabs.io. However, the specific IP addresses are not provided in the available content. You may need to perform a DNS lookup or contact ElevenLabs support for the exact IPs.

  3. Troubleshooting SIP Status 488:

    • SIP status 488 indicates "Not Acceptable Here," which often relates to codec or media negotiation issues. Ensure the following:
      • The audio sample rate is set to 48kHz, as required by ElevenLabs.
      • Both platforms support compatible codecs.
      • Verify that UDP traffic for RTP media streams is allowed through your firewall.

If you continue to face issues, you may need to escalate the matter to ElevenLabs or Twilio support for further assistance.

A SIP status code of 488 (Not Acceptable Here) typically indicates that there is a mismatch in the media or codec settings between the two systems. Here are some steps to troubleshoot and resolve this issue when using Twilio with ElevenLabs:

1. Check Audio Codec Compatibility

  • ElevenLabs requires audio to be in 48kHz sample rate. Ensure that your Twilio SIP trunk and PBX system are configured to support this.
  • Verify that the codec being used (e.g., G.711, Opus, etc.) is compatible with both Twilio and ElevenLabs.

2. Firewall and Network Configuration

  • Ensure that your firewall allows SIP traffic and RTP media streams. For SIP, the ports are typically:
    • 5060 for UDP/TCP
    • 5061 for TLS
  • Confirm that RTP traffic is not being blocked, as this can cause media negotiation failures.

3. Inspect SIP INVITE Headers

  • Check the SIP INVITE headers being sent from Twilio to ElevenLabs. Ensure that the From and To headers, as well as the Contact field, are correctly formatted.
  • Make sure the SIP domain matches ElevenLabs' SIP server (e.g., sip.rtc.elevenlabs.io).

4. Twilio ACL Configuration

  • If you're using IP-based authentication, you need to add ElevenLabs' IP addresses to Twilio's Access Control List (ACL). Unfortunately, the specific IP addresses for ElevenLabs are not provided in the available documentation. You may need to contact ElevenLabs support directly for this information.

5. Check Twilio Call Logs

  • In your Twilio console, navigate to Monitor > Call Logs and inspect the details of the failed call. Look for any additional error messages or clues about the 488 response.

6. Test with Simplified Configuration

  • Temporarily disable any advanced features like encryption or custom headers to see if the issue persists. This can help isolate the problem.

If the issue continues, you may need to escalate the problem to both Twilio and ElevenLabs support teams. Provide them with detailed SIP logs, including the full INVITE and response messages, to help diagnose the issue further.
