The Cisco 7910G IP Phone

The Cisco 7910G IP Phone, shown in Figure 4-4, is a low-end phone that is part of the same family of phones as the Cisco 7960G and 7940G. The primary difference is that the Cisco 7910G phone has only a two-line display and no softkeys. The Cisco 7910G supports English only and does not support XML capabilities.

Hardware

The Cisco 7910G IP Phone comes in two flavors: the Cisco 7910G and the Cisco 7910G+SW models. The Cisco 7910G has a standard 10 Mbps Ethernet interface, and the Cisco 7910G+SW is equipped with two 10/100 Ethernet interfaces. The ports are marked as 10/100SW and 10/100PC, respectively. The functionality of the ports is similar to the Cisco 7960G IP Phone, where one port can be connected to a LAN switch and the other port can be connected to a PC.

The Cisco 7910G supports only a single line (extension) and has a two-line, text-only LCD screen. The phone does not have a microphone, although it does have a "listen-only" speakerphone. If you put a call on "listen-only" speakerphone, the far-end party can't hear you. The phone has fixed function buttons for two speed dials, redial, hold, conference, transfer, accessing voice mail, and configuring call-forward from the phone.

Configuring the Cisco 7910G IP Phone

Configuring network parameters for a Cisco 7910G is similar to doing so for a Cisco 7960G IP Phone. The phone's default behavior is to use DHCP to obtain the network parameters. You can also manually configure these parameters from the phone by unlocking the phone and disabling DHCP services first.

Pressing the Settings button takes you through a menu with various options. This menu is comparable to the Settings menu for a Cisco 7960G. Because of the limited display and softkeys available, some of the functions on this menu work differently on a Cisco 7910G IP Phone than on a Cisco 7960G.

To unlock the phone, press the key combination **# before pressing the settings button. You can see the lock's status in the top-right corner of the LCD screen after pressing the settings button.

The menu gives you the following options, with a number assigned to each option:

• Handset Vol
• Speaker Vol
• Ringer Vol
• Model Information
• LCD Contrast
• Network Config
• Ringer Type
• Timers

Do the following to unlock the phone and disable DHCP services:

As soon as the DHCP service is disabled, you can manually configure the IP address, subnet mask, and default gateway.
