No response for SIP INVITE

Hello,

Since this morning i’ve got no reply at all from OpenAI SIP endpoint.

172.65.182.150 sip. api. openai .com

No matter if it’s a SIP Options (ping) to monitor the endpoint or directly SIP INVITE.

@Sean-Der is there something wrong with SIP Endpoint ?
Or maybe my server is banned for unkown reasons ?

Thanks,

Ed

Seems that it works again.

Maybe a temporary issue.

Erratum, got the same issue again here’s a little PCAP.

We can see that the INVITE is well sent to OpenAI (obviously obfuscated because of TLS)

But we can’t see any “SIP” response, just some random tiny tcp packet.

Still in this scenario.

Now i can see i receive some replies to my INVITES.

But the responses is not linked to my INVITE in any way.

Here’s a table resuming the exchange i’ve got from OpenAI endpoint. (slighly obfuscated)
We can see that i send an INVITE for a specific Call-ID and that OpenAI reply to another one. (not known).
I can confirm that, at this very same time, my server doesn’t send any INVITE for any other call. And certainly not with 02335**** “From” part.

So my server doesn’t know at all this Call transaction and so doesn’t reply (that’s why OpenAI try to resend in loop the OK SDP)

@Sean-Der I think there’s something broken on your side.
