Scenario With the scheduled release of Packet Tracer v5.3 in the near future, this case study is designed to provide you with an insight into some of the new features. Here you will be working with the new IP Telephony features, where you will be configuring Call Manager Express, setting up dial peers and connecting IP phones aswell as analogue phones. This activity is designed to provide you with an insight into what is now possible within Packet Tracer, how to use the various telephony devices, and finally how to apply the configuration. For the purposes of this activity we will assume that Company XYZ has two remote buildings. Each building contains a router configured with DHCP, CME, & other telephony features. Italso contains a Multilayer Switch configured to handle voice packets, and finally there are a number of telephone devices. The telephone devices vary, in some cases; the phones located within the buildings are IP Phones, or IP Communicators, or Analogue Phones. All phone devices must be able to call one another internally within a building as well as being able to call phones located within otherbuildings. You will need to work through the steps provided within this document, completing the configuration and inserting the various devices where needed.
Learning Objectives To explore the new features of Packet Tracer v5.3 Configure basic router & switch functions Configure DHCP, Call Manager Express, Dial Peers, & Telephony Features
Topology Diagrams The topology that you should endwith is shown below:
The topology that you start with is shown below:
Tasks Step 1: ‘Building_One_Router’ needs to be configured for DHCP to provide addressing for each IP Phone to be connected. Once DHCP is configured, you will need to configure the FastEthernet0/0 interface and ensure that the IP Phone connected to the multilayer switch receives an IP Address. For ‘Building_One_Router’,apply the following dhcp configuration:
Building_One_Router>enable Building_One_Router#configure terminal Building_One_Router(config)#ip dhcp pool CATC Building_One_Router(dhcp-config)#network 22.214.171.124 255.0.0.0 Building_One_Router(dhcp-config)#default-router 126.96.36.199 Building_One_Router(dhcp-config)#option 150 ip 188.8.131.52 #Sets the DHCP pool name: CATC# #DHCP network 184.108.40.206 with /8 mask##Specifying the default router# #Supports Cisco IP Phone requirement for DHCP#
Building_One_Router(config)#interface FastEthernet0/0 Building_One_Router(config-if)#ip address 220.127.116.11 255.0.0.0 Building_One_Router(config-if)#no shutdown
#Selects the Fa0/0 interface for configuration# #Applying the IP address# #Activating the interface#
Verify that ‘IP Phone 1’ has received an IP address byplacing your cursor over the phone until a configuration summary appears. (This may take a short while - please be patient).
Step 2: In order for ‘Building_One_Router’ to handle voice packets, you must now configure the Call Manager Express telephony service. You will also need to specify the maximum number of phones that the router will support and dial numbers.
For ‘Building_One_Router’ applythe following configuration:
Building_One_Router(config)#telephony-service Building_One_Router(config-telephony)#max-ephones 5 Building_One_Router(config-telephony)#max-dn 5 #Configuring the router for telephony services# #Setting the number of phones# #Setting the number of directory numbers#
Building_One_Router(config-telephony)#ip source-address 18.104.22.168 port 2000 #IP Address source#Building_One_Router(config-telephony)#auto assign 4 to 6 Building_One_Router(config-telephony)#auto assign 1 to 5 #Automatically assigning ext numbers to buttons# #Automatically assigning ext numbers to buttons#
Step 3: Switchport’s Fa0/1 – 5 on ‘Building_One_Switch’ need to be set to ‘voice’ in order to handle voice packets belonging within VLAN 1. For ‘Building_One_Switch’ apply the following...
