Teams Meeting being joined by an unknown user every time

Hello Teams Community,

Please I need your help on this.

A test meeting was done during our video conferencing Teams Meeting. A Cisco Telepresence Systems was used to join the Video Conferencing Teams Meeting with a VTC Id as shown here


But suddenly an Unknow User (T) also joined the meeting as shown here.


So we would like to know why the Unknown user joined the meeting.

Hi @66304432

Is this user is your guest in your organization?

How did these unknown user join in your Teams meeting? Did you send the meeting invitation link to others?
