As we know VoIP system basically is used to create a local calling network, with this we can create a calling system with in a LAN network. I will try to provide you VoIP phone service for best VoIP call.

But in this tutorial we are going to work on Cisco packet tracer, after drag all of them then we have to configure IP phone attach adapter with them. Then you have to do following configuration on switch


  • Vlan 10
  • Name Voice
  • Exit
  • Int ra fa0/2-3
  • Switchport mode access
  • Switchport voice vlan 10
  • Exit
  • Int ra fa0/4-24
  • Shut
  • Int fa0/1
  • Switchport mode trunk
  • Wr

I select Fa0/2-3 because IP phone connected with those switch ports, and shutdown all other ports for security purpose ok, now we have to configure Router.

  • Int fa0/0
  • No shut
  • In fa0/0.10
  • Encapsulation Dot1Q 10
  • Ip add x.x.x.x x.x.x.x
  • Exit
  • Ip dhcp excluded-address x.x.x.x
  • Ip dhcp pool Voice
