I’m trying to wireup WhatsApp Business Calling API SIP support to OpenAI Realtime SIP support. WhatsApp SIP does not support customizing the username portion of the SIP INVITE it sends to openai. Is it possible for openai to read the openai project ID from a user uri param? Ex: WhatsApp supports this pattern with request URI - INVITE sip:+123456789;project_id=open-ai-project-id@sip.api.openai.com:5061;transport=tls. The username portion in this URI is the WhatsApp Business number that is called by WhatsApp consumer.
This is a common way to carry identifying metadata and follows similar approaches used by TGRP, Genesys etc.
Thanks
