The Cisco 7902G IP Phone

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.

Hardware

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.

The Cisco 7935 and 7936 IP Conference Station

The Cisco 7935 and 7936 IP Conference Stations are IP-based, hands-free conference room stations . Figure 4-8 shows the Cisco 7935 IP Conference Station.

Figure 4-8. Cisco 7935 IP Conference Station

Hardware

The Cisco 7935 and 7936 conference stations provide a speakerphone for a large conference room. The general look and feel of the Cisco 7935 and 7936 are the same. Both have 10/100 Mbps Ethernet interfaces to connect to a LAN switch and operate from a 19V DC external power supply. The Cisco 7935 and 7936 do not support inline power.

The conference station has standard dial pad, off-hook, volume control, and mute buttons. Additional buttons are available on the phone to configure and navigate through the network and phone parameters.

The conference station does not have a handheld receiver. Hence, the phone's off-hook button should be used to make a call. The Cisco 7935 can cover a 10 ft. by 12 ft. (3 m by 3.6 m) conference room, and the Cisco 7936 can support a room as big as 20 ft. by 30 ft. (6 m by 9.1 m). The Cisco 7936 has two external microphones that can be connected to the main unit.

Configuring the Cisco 7935 and 7936 Conference Stations

Configuring a Cisco 7935 or 7936 conference station is similar to doing so with the IP phones mentioned in the previous sections. You can manually configure the phone's network parameters from the phone in a similar fashion. The Cisco 7935 and 7936 should be configured with their respective device types when configured under Cisco CME.

The menu button on the conference station provides access to network and phone-specific parameters. This menu is slightly different from the one on the phones discussed in the previous sections. You can access the network parameters by selecting the option admin setup. This menu is password-protected; it comes with a factory default password of 12345. As soon as you have access to this menu, you can change or edit the conference station's network parameters.

The Cisco 7920 Wireless IP Phone

The Cisco 7920 Wireless IP Phone, shown in Figure 4-9, is an 802.11b wireless communication device supported by Cisco CME.

Hardware

The Cisco 7920 Wireless IP Phone needs a Cisco Aironet 802.11b access point to work with Cisco CME. The phone uses a Lithium-ion battery for power; it can be charged using an external AC adaptor.

This phone has the following buttons :

A standard dial pad button
A left and right key that activates the softkey above it
An answer/send key to answer a call or send the number
Arrow keys to navigate through the phone menu
A power/end key to turn off the phone, silence a ringing call, or end a connected call

You can configure up to six lines on the Cisco 7920 Wireless IP Phone.

Configuring the Cisco 7920 Wireless IP Phone

The Cisco 7920 Wireless IP Phone is supported by Cisco CME 3.0 and later. This phone is configured like any other wireless device. Go to http://www.cisco.com/go/wireless for more information on setting up your wireless network for voice traffic.

The Cisco CME configuration required for a Cisco 7920 Wireless IP Phone is no different from any of the other IP phones discussed in the previous sections. This phone requires certain firmware depending on the version of Cisco CME you are using. This firmware version should be configured in telephony-service configuration mode. You also can configure the phone manually from the phone's menu.
