3.1 Network Configuration
The first step in using the VOIP 2747 IP Phone is to set the network
configuration to let the IP Phone connect to internet. This step depends on
your network environment and phone models, so please use the proper
method in configuring the IP Phone for your internet connection.
3.1.1 Dynamic IP Method (DHCP)
Most of the network environment in an office, hotel room or at home is
under a NAT (IP sharing)/router device. Under this environment, the easiest way
to connect to internet is using DHCP. The IP Phone, when configured using the
following method, will get the IP parameters dynamically, and connect to the
internet automatically.
Configure ► Password ：135 ► Network ► (Yes/No) Dynamic IP
Please press “ok” key to set Yes on (Yes / No) Dynamic IP when using
DHCP.
Most cable modem connections also use DHCP.
