The Cisco Call Manager Express (CME)
software has a new name, Cisco Unified Communications Manager Express. However,
it provides the same service, namely IP Telephony that runs on Cisco Integrated
Services routers. The Cisco 7921 IP Phone is one of a series of VoIP phones in
the catalog. It uses the wireless standards 802.11a, b, and g and it has 2.4and
5 Ghz capabilities. Its other features are a built-in speaker phone and a
two-inch display. A diversity antenna is available for better radio frequency
coverage.
Main
Features of Cisco Unified Wireless IP Phone 7921G
The Cisco Unified Wireless IP Phone 7921G
supports a host of calling features and voice-quality enhancements. The device
is an advanced media IP phone, delivering wideband audio capabilities. In
addition to wideband audio, Cisco Unified Wireless IP Phone 7921G supports
presence, which enables users in a mobile Wi-Fi environment to view the current
status of other users. Because the Cisco Unified Wireless IP Phone 7921G is
designed to grow with system capabilities, features will keep pace with new
system enhancements.

Call
Manager Express you need first.
Configuring
a Cisco Unified Wireless IP Phone 7921 with Call Manager Express Step by
Step
1. Type
"enable" to enter the router privilege mode. In this mode, you can
configure the router and set up the 7921 IP Phone commands. The privilege mode
looks like this: "Router#." (Exclude the period.) Privilege mode
contains an editor that opens automatically. You type all commands within the
editor, but there are different modes depending on the type of command you are
typing. You get to those modes automatically by typing the command to initiate
the mode. (Note: in these commands, case is not important.)
2. Type
"ip dhcp pool VOIP" followed by "network 11.1.9.0
255.255.255.0" followed by "option 160 ip 11.1.9.1 lease 8."
This command sets up a DHCP (Dynamic Host Configuration Protocol) pool, a
leased range of addresses given to network devices. The network term identifies
the routing network on the router. The option number identifies the location of
the tftp server on the Vlan (Virtual Local Area Network)and where the CME is.
3. Type
"Interface Fastethernet0/0" followed by "description Internal
Vlan" then followed by "ip address 192.168.9.4 255.255.255.0."
(Exclude the last period.) Here, you have configured an Ethernet port on the
router.
4. Type
"interface fastethernet0/0.2" followed by "description VoIP
Vlan" with the next command as "encapsulation dot1q 2" and
ending with " ip address 11.1.9.1 255.255.255.0." (Exclude the last
period.) Now you have identified the tftp server, which houses the CME. The
next step will set up the 7921 phone.
5. Type
"ephone-dn 1" followed by "number 99." Then type "label
EntOffice" and ending with "name EntOffice." (Exclude the last
period.) The reason you type in "number 99" (not just 99) is that the
office phone extension is 99.
6. Type
"ephone 1" followed by "description home office" and then
"mac-address 0018.95AF.2b73." (Exclude the last period.) The last two
commands are "type 7921" and "button 1:1 2:2." (Exclude the
last period.) The "mac address" is the phone's serial number address.
The type is the 7921 phone system, and the button command maps the phone
buttons to the ephone-dn. This allows automatic configuration of the dial peer
(the end point of a phone call - where you are calling) and virtual voice ports
with the buttons on the phone.
