IP Phones

IP Phones function as a telephone to the Meridian 1and CS 1000 systems.

The IP Phone encodes voice as binary data and packetizes the data for

transmission over an IP network to the Call Server, to the Terminal Proxy

Server (TPS), or to another IP Phone.

The Phase II IP Phones (IP Phone 2001, IP Phone 2002, and IP Phone

2004), IP Audio Conference Phone 2033, and IP Softphone 2050 can act

as a DHCP client in one of two modes:

•

partial DHCP mode

• full DHCP mode

The IP Phone 2007, IP Phone 1110 Series, and IP Phone 1200 Series act

as a DHCP client in auto DHCP mode.

IP Phone parameters can be entered manually or obtained automatically.

For more information, see “Provisioning the IP Phones” (page 447).

All the IP Phone configuration parameters can be entered manually. Each

IP Phone requires the network configuration parameters, Connect Server

parameters, IP Telephony node ID, and Virtual TN. If there are a number

of IP Phones to configure, manual configuration is time-consuming and

prone to error. Using full or partial DHCP or auto DHCP to automatically

configure the IP Phones is more efficient and flexible. This ensures that

current information is used.

Auto DHCP mode

When an IP Phone 2007, IP Phone 1110 Series, or IP Phone 1200 Series

is configured to operate in Auto DHCP mode, the DHCP Server provides

the network configuration parameters from the DHCP server.

Partial DHCP mode

When the Phase II IP Phone (IP Phone 2001, IP Phone 2002, and IP

Phone 2004), IP Audio Conference Phone 2033, or IP Softphone 2050 is

configured to operate in partial DHCP mode, the DHCP server needs no

special configuration to support IP Phones. The IP Phone receives the

following network configuration parameters from the DHCP server:

• IP address configuration for the IP Phone

• subnet mask for the IP Phone IP address

• default gateway for the IP Phone LAN segment

In partial DHCP mode the Connect Server parameters, node ID, and

Virtual TN must be entered manually.
