Hello everyone, in this tutorial I’ll discuss about how to configuration VoIP on Cisco Packet tracer. This is topology that will used on.
In this lab we will use the following devices :
- Router 2811
- Switch
- IP Phone 7960
Configuration Router
First step we will configure the router as the following
Enable interfaces : Router>enable Router#configure terminal Router(config)#hostname R-VoIP R-VoIP(config)#int fa0/0 R-VoIP(config-if)#no shut R-VoIP(config-if)#exit R-VoIP(config)#
Then Create sub interface on R-VoIP with vlan-id is 10 because we will use vlan 10 on this tutorial :
R-VoIP(config)#int fa0/0.10 R-VoIP(config-subif)#encapsulation dot1Q 10 R-VoIP(config-subif)#ip add 192.168.10.1 255.255.255.0 R-VoIP(config-subif)#exit
Configure DHCP Server on R-VoIP dan setup dhcp option 150 for ip-phone communication
R-VoIP(config)#ip dhcp excluded-address 192.168.10.1 R-VoIP(config)#ip dhcp pool DHCP_PHONE R-VoIP(dhcp-config)#network 192.168.10.0 255.255.255.0 R-VoIP(dhcp-config)#default-router 192.168.10.1 R-VoIP(dhcp-config)#option 150 ip 192.168.10.1 R-VoIP(dhcp-config)#exit
Configuration Telephone Service. max-dn and max-ephones values are adjust to how many numbers of ip-phone that will used. ephone-dn command used for assign phone number of each dn.
R-VoIP(config)#telephony-service R-VoIP(config-telephony)#ip source-address 192.168.10.1 port 2000 R-VoIP(config-telephony)#max-dn 3 R-VoIP(config-telephony)#max-ephones 3 R-VoIP(config-telephony)#auto assign 1 to 3 R-VoIP(config)#ephone-dn 1 R-VoIP(config-ephone-dn)#number 0811 R-VoIP(config-ephone-dn)#exit R-VoIP(config)#ephone-dn 2 R-VoIP(config-ephone-dn)#number 0812 R-VoIP(config-ephone-dn)#exit R-VoIP(config)#ephone-dn 3 R-VoIP(config-ephone-dn)#number 0813 R-VoIP(config-ephone-dn)#exit R-VoIP(config)#
Configuration Switch
Configuration switchport and vlan :
SW(config)#int fa0/1 SW(config-if)#switchport mode trunk SW(config-if)#exit SW(config)#vlan 10 SW(config-vlan)#name VOICE SW(config-vlan)#exit SW(config)#int range fa0/2-4 SW(config-if-range)#switchport mode access SW(config-if-range)#switchport voice vlan 10 SW(config-if-range)#exit SW(config)#
Configuration IP Phone
Turn on Ip Phone with drag and drop power adaptor icon as the following :
Then move to GUI Tab and make sure the ip phones already got the phone number as the following.
Testing for Calling :
Calling is successfull.

Thanks for the guidelines you have shared here. One more thing I would like to express is that computer system memory specifications generally rise along with other breakthroughs in the technological know-how. For instance, when new generations of processors are made in the market, there’s usually a corresponding increase in the dimensions preferences of both the computer system memory along with hard drive space. This is because the software program operated by simply these processors will inevitably increase in power to make new technology.
