The Cisco 7902G, shown in Figure 4-7, is the lowest-end IP phone in the portfolio supported by Cisco CME. The phone's physical appearance is similar to a Cisco 7905G IP Phone but without an LCD screen.
Figure 4-7. Cisco 7902G IP Phone
The default configuration of network parameters for a Cisco 7902G IP Phone is via the DHCP mechanism. Because of the lack of display, manual configuration is carried out via a built-in English-only interactive voice response (IVR) menu on the phone. The Cisco 7902G has a single 10-Mb Ethernet interface and requires a 5V DC external power supply to operate.
The four fixed function buttons provide redial, transfer, conference, and voice mail functionality. You can configure up to ten speed dials for a Cisco 7902G. To place a call using speed-dial, press and hold (for about two seconds) the number on your keypad (0 to 9) assigned as a speed-dial number.
Configuring the Cisco 7902G IP Phone
The Cisco 7902G IP Phone has hold and function keys. Pressing the hold button puts an active call on hold. The same action retrieves a call if one is on hold. Pressing the function button when the phone is off-hook activates the IVR menu that allows you to manually configure the phone's various network and service parameters.
