Introducing Cisco Unified MeetingPlace Web Conferencing
How Users Connect to Web Conferencing
Users connect to the Web Conferencing home page to sign in, schedule or find meetings to attend, and
update their profile settings. This connection uses the primary IP address (or hostname) configured on
the Web Conferencing server and port 80.
When a meeting is scheduled to begin, the Cisco MeetingPlace Agent Service instructs the web engine
to initiate the meeting. As users join the web component of the meeting, the Flash-based meeting console
is downloaded on their desktops, allowing them to connect to the Flash Media Server running on the Web
Conferencing system by using the secondary IP address (or hostname) configured on the server.
The meeting console communicates with the Flash Media Server on the Web Conferencing server
through TCP port 1627, as shown in
establishes a tunnel connection over HTTP through port 80. This process allows the meeting console to
bypass firewall restrictions so that external users can participate in web conferences.
The web server also supports tunneling over HTTPS by using Secure Sockets Layer (SSL).
