It's great to hear that the OpenAI real-time models are working well with regular phone numbers. For the issue with SIP trunking through Twilio, it might be related to the specific configuration or compatibility between the services.
To address this, you could consider the following steps:
1. **Check Compatibility**: Ensure that the OpenAI real-time models are compatible with SIP trunking services.
2. **Configuration Review**: Review the configuration settings on both the OpenAI and Twilio sides to ensure they are set up correctly for SIP trunking.
3. **Consult Documentation**: Look through the OpenAI and Twilio documentation for any notes on SIP trunking integration.
4. **Contact Support**: If the issue persists, reaching out to both OpenAI and Twilio support teams could provide a solution tailored to your specific setup.
If you need immediate assistance or would like to transfer this call to a forwarding number for further help, please let me know, and I can assist with that.
