Title: Error 7504 - Cannot join Teams meeting with Application-hosted Media Bot

[validimadigitsore]

Hi,

I'm developing a Teams bot with application-hosted media for real-time audio capture and transcription.

Environment:

• App ID:
• Tenant ID:
• Region: West Europe
• VM: Windows Server 2022, .NET 8.0

What I've configured:

• Graph API permissions granted with admin consent:
• Calls.AccessMedia.All
• Calls.Initiate.All
• Calls.JoinGroupCalls.All
• Calls.JoinGroupCallAsGuest.All

Resource Account created: meetingbot@digitstore.ro
Application Access Policy created and applied globally
Teams license assigned to Resource Account
MediaPlatform initialized successfully (4 vCPU VM)
SSL certificate configured

Error when calling JoinMeetingAsync:
{
"error": {
"code": "7504",
"message": "Insufficient enterprise tenant permissions, cannot access this API"
}
}

Question:
Does this tenant need to be explicitly provisioned by Microsoft for the Graph Communications Calling API?

If yes, could you please enable it for my App ID and Tenant ID listed above?

Thank you!

This sounds like the teams meeting you are asking the bot to join belongs to a user that is not in the same tenant as the one you have the bot permissions to.

To test things you could use .the bot identity to create the meeting (bot can't be the owner so you'll need to provide a user that is in your target tenant to be owner). Then join that meeting, that might help you identify tenant privilege problems.
