Which call launch option in TMS reserves the room and generates the call route?

Automatic Connect both reserves the room and generates the call route, but it also automatically dials out to all participants at the scheduled time, making it more than just a reservation with route generation.

Reservation only books the endpoint to prevent scheduling conflicts but does not generate or pre-configure the call route for the meeting.

One Button to Push pre-configures the call so a user can initiate it with a single button press on the endpoint, but the call route is not stored in advance the same way No Connect prepares it.

No Connect reserves the room endpoint for the scheduled time slot and generates the complete call route in TMS, but does not initiate the call - participants must dial in manually. This option is useful when organizers want to block the resource and have the routing pre-calculated without an automated dial-out. It combines resource reservation with route generation while leaving call initiation to the participants.
