Hi All

I have the .net client SDK sample app running on my PC. Everything looks fine as i can recieve audio and video. My only issue is that i can't send my audio. I ran Equinox on same PC and its working fine. Any Suggestion?

Note: .net sdk 4.1 download link seems broken.

Thanks a lot.
Amr

Thank you for your feedback, the link to Client SDK 4.1 for Windows will be fixed as soon as possible.

In order for us to help you debug the audio issue we need to review the logs that your client generates, specifically Client SDK logs. Client.LogMessage interface helps capture Client SDK logs in the application if the standard .NET log routing is not an option.

Thanks Artem

When i run using visual studio and while voice call is running i get the below in output:

This is a known issue that is fixed in Client SDK 4.1.

Thanks,
Is the download link for 4.1 .net sdk fixed. Can you provide an alternate temp link to download it?
