Communication Service Ports used for Polycom Management Software applications
Communication across the network for Polycom products requires the usage of certain Internet
service ports. Global Management System communicates with the web client, video devices
and other services. In the tables below, “Direction” indicates how a particular communication is
initiated; for example, “Web browserà Global Management System” means the web browser
opens a connection with Global Management System which is then used to interchange
information.
The Web Client
The web client is a web browser running on a PC station that is used to access Global
Management System, Path Navigator, or video devices. The table below shows the protocol
and port used. The ports listed must be open for two-way communication.

Different features offered in Global Management System use different ports when
communicating with video devices. The port most often used is port 80. However, other
protocols such as FTP and Telnet require the usage of ports other than 80.
