Getting CallEndReason not in documentation using CallingQuickStart WinUI App

Question

Hi

I have downloaded and built the quickstart windows app CallingWinUI (https://github.com/Azure-Samples/communication-services-dotnet-quickstarts/tree/main) for calling with azure communication services. I am making a call and it gets disconnected with a call end reason that is not in the documentation. Can anyone tell me what this reason is.

Code:400

SubCode:580042

Thanks

Hi @Daniel Woodnutt ,
Thanks for the question and using MS Q&A platform.

Hey, it looks like the call ended with Code: 400 and SubCode: 580042, which isn't covered in the provided docs. The context mostly explains specific PSTN call response codes but doesn't mention this subcode.

For issues like this, double-check your network setup, make sure you're using the latest SDK, and confirm your app is set up correctly for calls. If you're still having trouble, you might want to reach out to Microsoft support for more help.
