— If DHCP (Distributed Host Control Protocol) service on the system is active or the
Customer DHCP server has been configured to hand out the specific system network
details, the IP telephone automatically attempts to find the server.
After you register the telephone to the system, as described in “Registering the telephone
to the system” on page 50 , the telephone assumes the parameters it receives from the
system, which are described in “Configuring telephone settings” on page 50 ).
— If DHCP is not configured to provide system information, or if you are not using DHCP on
your network, you must configure your telephone parameters before the telephone can
register to the system. In this case, follow the directions in
“Configuring telephone
settings” on page 50 , and then follow any of the prompts that appear, as described in
“Registering the telephone to the system” on page 50 .
— If an external DHCP server is not present, the DHCP server on the main unit supplies IP
configuration information for all IP devices (PCs and IP Phones). It also supplies specific
connection information to the IP Phones.
Registering the telephone to the system
When you first connect the telephone to the IP connection, you receive one of the following:
• If the telephone is not yet registered, and when a password is entered in the Terminal
Registration screen, the telephone prompts you for that password.
• If Auto Assign DN is not selected, the telephone prompts you for a DN. Refer to the Device
Configuration Guide (NN40020-300) for more information on configuring telephones.
• If you are prompted for a password, enter the password and press OK.
• If you are prompted for a DN, enter the DN you want assigned to this telephone and press OK .
When the telephone registers, it downloads the information from the system IP Telephony record
to the telephone configuration record. This can include a new firmware download, which occurs
automatically. If new firmware downloads, the telephone display indicates the event.
Configuring telephone settings
If you are not automatically registered to the system, you can configure the telephone settings to
enable you to access a system on the network. You also must perform these steps if your
IP telephone is not connected to the same LAN to which the system is connected.
Note: If the telephone displays a prompt that indicates it cannot find the server, follow
the instructions in “Configuring telephone settings” on page 50 to enter the specific
network path. “Troubleshooting IP telephones” on page 55 describes other possible
prompt messages.
