Hello I just setup an account on Vapi and am quite excited about the Squad option, which is something I've been looking for a few apps. I have number setup with Telnyx, but when I call it, it doesn't pick up. The Telnyx Logs show a failed call, with Response Code 400. The sip connection seems to work according to the logs (see image attached) On the Telnyx side : Delivery ID : 515e1598-4f6e-4a77-baca-63fad8767c5b Started at Mar 19, 2025, 4:37:13 PM call_control_id : "v3:iTeqCKn9nP47oE2JRrkaLrCLlSLbR2H4-CfLMNwBQ_-0vK82QFHwRQ" "connection_id": "2654587949366117633", "start_time": "2025-03-19T15:37:13.529037Z", "to_sip_uri": "+3226010688@185.246.41.140:5060" On the Vapi side I can only see Webhook logs, with Org ID : 5d8ff131-cca0-476c-a8f3-9d8f98cf3af0 Thanks

Hey Ouranos, can you share the phone number ID? This will help me understand what could have been going wrong for you.

Hey Ouranos, the dashboard method of importing Telenyx numbers is having some issues, which is why even after importing it, you are unable to use it. So, I will suggest removing the number and then integrating the Telenyx number with VAPI over the SIP trunking process. Here is the link to the documentation for importing the numbers:
