It always worked but now It just hangs up. I use a Dutch Twillio imported number. Geo permissions are setup right.

@Aristoic I'm sorry to hear that you're experiencing issues with your Twilio service. It sounds like there might be a problem with the call handling logic or a recent change in your configuration that's causing the calls to hang up. To assist you better, could you please provide me with more details about when the issue occurs? Is it happening during the voicemail detection process or at a different point in the call flow?

When I call the agent it rings 2-3 times and it hangs up

@Aristoic The description is not specific enough to identify the cause of failure. - What you need to do is assign a server URL to the phone number using the API, and then make another call. - After that, Vapi will send debugging artifacts to your server. - In these debugging artifacts, you will find the reason for the failure. From our side, it won't be possible to identify the issue.
