We understand that you are looking to connect to a Teams meeting with an ID and password rather than meeting link. At this time connecting to a Teams meeting using a meeting ID and password is not supported by Azure Communication Services. Azure Communication Services Calling SDK accepts a full Teams meeting link, which can be retrieved using Graph APIs or from the Join Meeting URL in the Teams meeting invite itself.
You can find more information about joining a Teams meeting from a Windows app here.
We invite you to share any feedback you might have here. This is reviewed by the product group for ideas on what features to add next.
If you have any further questions or concerns, please reply on here so we can assist you further.
