Case Study# 2
Instructions:
To configure the Cisco Unified Communications Manager Express click on the console host icon
that is connected to a Cisco Unified Communications Manager Express by a serial console cable
(shown in the diagram as a dashed black line).
You can click on the buttons below to view the different windows. Each of the windows can be
minimized by clicking on the [-]. You can also reposition a window by dragging it by the title bar.
The “Tab” key and most commands that use the “Control” or “Escape” keys are not supported
and not necessary to complete this simulation. The help command does not display all
commands of the help system.

Scenario:
You are required to manually configure a Cisco Unified Unified Communications Manager
Express to support two IP phones with directory numbers starting with 5001.
The phones need to be configured as dual-line phones as per the following table:
The Cisco Unified Communications Manager Express should be configured as a DHCP and TFTP
server.
The IP phones should obtain their IP addresses via DHCP in the range 10.3.130.10 –
10.3.130.254. IP addresses in the range 10.3.130.1 to 10.3.130.9 should be excluded.
The IP phones are connected to an EtherSwitch module, interface GigabitEthernet1/0 on a Cisco
2811 router as per the topology diagram. The voice VLAN ID is 130 and default router for the IP
phones is 10.3.130.1.
The EtherSwitch module has been preconfigured and is not configurable.
You are also required to configure a second directory number 5010 as a shared directory number
on line 2 of each IP phone.
