    [Realtime API with SIP - missing Header in SIP - Asterisk][2]



      Summary: 

When establishing a SIP call using Asterisk with OpenAI’s Realtime API SIP endpoint, the call is prematurely terminated due to the SIP 200 OK response missing the required Content-Type: application/sdp header. This causes Asterisk to fail SDP negotiation and hang up with a SIP 406 error.

    [TIP: Chat Completions API reference - as a single request, for AI understanding][3]



      It is a constant need to expand sections of the API reference web site over and over to drill-down to particular parameters. It is dynamic, and cannot be scraped or copied. 

The AI models don’t trust what you provide because of pretraining, and will automatically “break” code passed through.
