API Bugs

Hi,

We are trying to entegrate Sinch contact PRO with OpenAI using a SIP trunk as described in:

https://platform.openai.com/docs/guides/realtime-sip

What we can see at Sinch side is that the invite is correctly sent but we are receiving a 400 error:

We are getting this error in every call, it is not an intermitent issue.

How can we check at OpenAI side the cause of this Bad Request error?

Project id is: proj_muwKrpgJ46Gg5uNvaKRImFUl

Thanks

Hi @rcastrillo1

Would you mind sending me a DM or email seaduboi @ openai and I can direct you to a dev server so I can debug easier.

thanks

Hi Sean,

Thanks for your answer. Finally, we have it working. The problem was that we were using secure RTP even SIP is TLS.
Connection is now forced to plain RTP and it is working.

Thanks and regards
