IP
The Internet Protocol (IP) is the protocol that supports data being sent from one computer
to another on the Internet. Each computer on the Internet has at least one address that
uniquely identifies it from all other computers on the Internet. When you send or receive
data, the message gets divided into units called packets. Each of these packets contains the
Internet address of the sender and the receiver.
IP is a connectionless protocol, which means that there is no established connection
between the end points that are communicating. Each packet that travels through the
Internet is treated as an independent unit of data without any relation to any other unit of
data. In the Open Systems Interconnection (OSI) communication model, IP is in layer 3,
the Networking Layer.
IP address
The Internet Protocol address is a unique identifier that allows communication over the
Internet to be directed to the appropriate destination. Every computer on the Internet must
have a unique IP address. IP addresses are allocated by an Internet service provider (ISP)
in the following format: nnn.nnn.nnn.nnn, where nnn is a numeric value from 0 to 255. IP
addressing might be referred to as being a static IP address or a dynamic IP address.
IP music
With this feature you can provide background music to the system from the IP network
instead of installing music source hardware.
IP telephones
Business Communications Manager IP telephones and WLAN wireless IP telephones can
make calls out of the system over land lines as well as VoIP trunks. The telephones are IP
telephones because they connect to the Business Communications Manager through an IP
connection, rather than a hard-wired connection. Once they connect to the system, the
Business Communications Manager converts the information as required for the trunk on
which the call is going out.
