VoIP Introduction

Configure VoIP in Cisco Packet Tracer so here you will learn that how you can implement VoIP (Voice over IP) in Cisco Packet tracer. Basically VoIP is used to transfer Voice from one place to another place using Data networks. In this tutorial we will create Local VoIP for business use. VoIP historically known to using ip address to connect private branch exchanges (PBXs), however the word is currently used synonymous with IP telephony.

How does VoIP work?

VoIP encapsulates audio with a codec in to data packets, transmits them over an IP system and then unencapsulates back them in to sound at the opposite end of this bond. VoIP end points comprise dedicated desktop VoIP phones, soft phone software running on PCs and mobile phones, and WebRTC-enabled browsers.

VoIP protocols and standards

VoIP endpoints on average utilize global Telecommunication Union (ITU) conventional codecs, including as for instance G.7 11, that’s the standard for transporting uncompressed packets, or G.729, which is the norm for compressed packets. Many tools suppliers also use their very own proprietary codecs. Voice quality may suffer when compression is employed, but compression minimizes bandwidth demands. VoIP on average supports non-voice communications via the ITU T.38 protocol for delivering faxes over a VoIP or IP network in actual moment.

Configure VoIP in Cisco Packet Tracer

Let’s start with it.
We need 1 switch 1 router and 3 IP phones and 3 Pc’s now first of all we have to make PC’s Connection Dynamic Host Configuration Protocol (DHCP) because we are going to use DHCP from the router.

    1. Now connect all the devices with each other
    2. Now turn on all the devices.
    3. Now we have to create VLAN In switch and assign that VLAN to ports.
    4. We create 5 VLAN’s 10, 20,30,40,50
    5. We will use 50 as native VLAN, as we know native vlan is used to carry untagged traffic or packets.

  1. Now assign VLAN to Ports, We will assign VLAN 10, and 20 to Fa0/2-4
  2. Vlan 40 to 5-24 because it’s for other purpose.
  3. VLAN 5 to port 0/1 because it will trunk with router.
  4. Create sub interfaces fa0/0.10, fa0/.20, fa0/0.50
  5. 10 for VLAN and 20 for VLAN 20 and 50 for native VLAN
