Does anyone know how to fix this error? An error occurred in this call: call.in-progress.error-sip-telephony-provider-failed-to-connect-call I'm using the private trunk I have today with a Brazilian operator.

Can you share the call ID?

Waited 300s But Transport Never Connected. @Leo Your telephony is not responding to INVITE SIP requests, can you check with them. https://cdn.discordapp.com/attachments/1366759882497458266/1366773168479670372/image.png?ex=68122a34&is=6810d8b4&hm=3fbe456e5f23c5efe6e48c610a76b65e09eac433e5fe7fdb18cef60e00f6972c& https://cdn.discordapp.com/attachments/1366759882497458266/1366773168756490252/callid-f6231851-9f97-123e-a893-0ec7040a32ad.pcap?ex=68122a34&is=6810d8b4&hm=6f40ea1e99338cf24eef8d113b83f3aa048ce86c0fba3e42806583ff052fc8df&

Of course I can, but is my authentication method correct?

for this you have to check with them, can't say anything.

Ok, I'll check with them and get back to you on this topic. Thanks

they need to connect on sip.vapi.ai instead
