(*) Note: While using MultiSite, if a site is disconnected and reconnected without terminating the
entire conference, the next site to be connected will have a H.245 port outside of the specified
range. If this functionality is required through a firewall, the range of TCP ports can be extended
past 5564. However, if a site is disconnected and reconnected, without ending the conference
enough times one can quickly end up outside of this range again.
