Please provide any relevant SIP codes, error logs, or messages associated with these calls.

To help track down this issue, could you share one or two: - When exactly this happened (the timestamp) - What response you expected to get - What response you actually got instead This would really help us figure out what went wrong!

I created a SIP trunk in Vapi and then assigned a number to it. After making calls using this number, every call failed with the error: call.in-progress.error-pipeline-no-available-llm-model I'm trying to understand what response Vapi is receiving from my SIP trunk. I need to identify what might be misconfigured on my side so I can fix the issue and get the trunk working properly. Please provide any relevant SIP responses or error details that Vapi is receiving when attempting to connect these calls. This call ids are from 2025-04-20T07:49:03.241Z

Looking into it

I am also facing the same error, I am using a free Vapi number and every time I want the agent to place a call I get this exact same error. I have tried to generate new numbers but no change. Please can someone help with what the problem could be?
