[SadevKalubowila]

Library name and version

Azure.Communication.Calling.WindowsClient 1.2.0

Query/Question

We are developing video calling UWP app based on (https://learn.microsoft.com/en-us/azure/communication-services/quickstarts/voice-video-calling/get-started-with-video-calling?pivots=platform-windows) document targeting HoloLens 2 and PC. There is currently a problem that there is a high probability that one party cannot see the other party upon video call establishment. 70% times the caller cannot see the responding party but the responding party can see the calling party.

I even tried this (https://github.com/Azure-Samples/communication-services-dotnet-quickstarts/tree/main/Calling) GitHub sample. The same problem was found to exist in the sample projects.

Environment

This occurs on Windows 11 Pro [Version 22H2, OS build 22621.2361] as well as on HoloLens 2.[OS Build 22621.1133]
.NET version 7.0.7
Azure.Communication.Calling.WindowsClient 1.2.0 SDK
Microsoft.NETCore.UniversalWindowsPlatform 6.2.14
Tried with x64 and x86 and ARM64 architectures.
Visual Studio Version 2022 (17.6.4)
