(2). When the input mode is in digit mode (you can only input ‘0’ – ‘9’ and ‘*’, ‘#’), and you want to input a character, please press “TXT ←→ NUM” key first to toggle to “character” input mode.

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.
