Inviting multiple participants into a remote control session.

During a remote control session use the collaboration function to invite other participants to join the session. This function is useful if you are connected to a target where the target user requires assistance and you need additional help to solve the problem. All controller users who join the session can see the target screen. The controller who initiates the collaboration session with the target is known as the master controller and it is this user who controls the activity in the session. For example, who is allowed to join, how many people are allowed to participate or who should have control of the session. All other controllers in the session are known as participants. When a new controller joins the session they can see the target screen in the session window but they do not have any control of the session and should request control when they need to work with the target. If user acceptance for collaboration is enabled, the target user will have the final decision on whether the new controllers can join the session. The value of the Enable user acceptance for collaboration requests server policy or the ConfirmCollaboration target property determines whether the target user should accept or refuse the request to join the session, depending on the type of collaboration session.

Yes
the target user is asked to accept or refuse the request to join the session. If they accept the request, the new controller is connected to the session. If they refuse, or do not respond in a given time, a refusal message is displayed and the new controller is not joined to the session.
Note: If the target user does not respond in the given time and the Acceptance timeout action server policy or AcceptanceProceed target property is set to PROCEED, you are connected to the session.
No
user acceptance is not required by the target user and the new controller is automatically connected to the session.
