KONFIGURASI VOIP ( 1 Router, 1 Switch dan 3 Ip Phone ) - Cisco Packet Tracer

Introduction

This tutorial provides a comprehensive guide for configuring a Voice over IP (VoIP) setup using Cisco Packet Tracer. By the end of this guide, you will understand how to connect one router, one switch, and three IP phones, enabling effective communication over your network. This setup is essential for anyone looking to implement VoIP systems for businesses or educational purposes.

Step 1: Set Up the Network Devices

• Open Cisco Packet Tracer.
• Add a Router:
  • Drag and drop a router from the device list.
• Add a Switch:
  • Select a switch from the device list and place it next to the router.
• Add IP Phones:
  • Place three IP phones within the workspace.

Step 2: Connect the Devices

• Connect the Router to the Switch:
  • Use a straight-through cable.
  • Connect one end to the router's GigabitEthernet port and the other end to the switch's FastEthernet port.
• Connect the IP Phones to the Switch:
  • Use straight-through cables for each phone.
  • Connect each IP phone to different ports on the switch.

Step 3: Configure the Router

• Access the Router CLI:
  • Click on the router and go to the CLI tab.
• Enter Configuration Mode:

  enable
  configure terminal
  

• Assign IP Address to the Router:
  • Choose an interface (e.g., GigabitEthernet0/0).

  interface GigabitEthernet0/0
  ip address 192.168.1.1 255.255.255.0
  no shutdown
  

Step 4: Configure the Switch

• Access the Switch CLI:
  • Click on the switch and navigate to the CLI tab.
• Enter Configuration Mode:

  enable
  configure terminal
  

• Assign VLAN to the Switch:
  • Create a VLAN and assign it to the ports connected to the IP phones.

  vlan 10
  name VoIP
  exit
  interface range fa0/1 - 3
  switchport mode access
  switchport access vlan 10
  

Step 5: Configure the IP Phones

• Access the Configuration Settings:
  • Click on each IP phone and go to the Desktop tab.
• Set the IP Address:
  • Assign static IP addresses in the same subnet as the router.
  • Example for Phone 1:

  IP Address: 192.168.1.2
  Subnet Mask: 255.255.255.0
  Default Gateway: 192.168.1.1
  

  • Repeat for the other two phones, incrementing the last octet (e.g., 192.168.1.3 and 192.168.1.4).

Step 6: Test the Configuration

• Ping Test:
  • Use the command prompt on each IP phone to ping the router’s IP address (192.168.1.1).
  • Ensure all phones can communicate with the router.

Conclusion

You have now successfully configured a VoIP setup using one router, one switch, and three IP phones in Cisco Packet Tracer. This configuration allows for basic communication over your network. For further learning, consider exploring advanced VoIP features such as QoS settings, call management, and integrating with additional applications.
