INSTALLING THE IP250D
2
1.2 TWO LINES
The IP250D can handle one or two calls simultaneously, much like a standard “two-line”
analog or digital telephone. However, there is only one line (or cable) connecting the
IP250D to the network.
1.3 THE NETWORK
Instead of telephone lines, the IP250D connects to other IP phones via an Ethernet network.
1.4 THE CALL CONTROL SERVER
A specialized network server, called a “SIP server” for SIP IP phones, or a “Call Agent”
for MGCP phones, controls all of the IP250D terminals, and other types of VoIP
terminals that are connected to the network.
1.5 THE NETWORK OR SYSTEM ADMINISTRATOR
The IP250D requires configuration in order to work properly on the network. This task
is performed by a technical specialist referred to as a network or system administrator.
The network administrator will perform the configuration steps from a control station.
2 Installing the IP250D
Installing the IP250D at an office desk or workstation is as simple as installing a
conventional office telephone.
