Bot is unable to join the call

[rose-ramasamy]

I am trying the Broadcast-Development-Kit solution and i want to extract the audio from the teams meeting.

I followed the Readme and set it up the application. I am able to run the application without any errors. However, Bot is not joining into the call.

I am sharing the config details and i have created app and bot in azure portal. Can you please help me with this issue?

ngrok configuration:

BotService appsettings.Development.json

BotOrchestrator local.settings.json
