Chapter 7-Reservations
When a Conference Profile is assigned to a Meeting Room or a Reservation,
the Profile's parameters are not embedded in the Reservation, and are taken
from the Profile when the reservation becomes an ongoing conference.
Therefore, any changes to the Profile parameters between the time the
Reservation or Meeting Room was created and the time that it is activated
(and becomes an ongoing conference) will be applied to the conference.
If the user wants to save the current parameters, a different Profile with
these parameters must be assigned, or a different Profile with the new
parameters must be created.
