Can make call, accept it but can not invite the user from same tenant to the call.

[bfany365]

Hi.

Project: Developed on .NET 4.8
Microsoft.Graph.Communications.Calls: 1.2.0.10563
Microsoft.Graph: 5.38.0

I have a bot registered as multi tenant, the same bot:

• Can read users from the tenant.
• Can make a call from the bot to the user of the tenant.

But if there is an incoming call, it fails if I want to add a user from same tenant to:

call.Participants.InviteAsync()
or

_botCall.TransferAsync()

It gives the following error:

Request authorization tenant mismatch.

Can somebody help ?
