In this tutorial, you will learn how to use IPBlue’s VTGO Lite softphone to test skinny phone registration and dialing by running multiple instances of emulated Cisco IP Phones.

This is the fourth tutorial in the Virtual Voice Lab Series for CCIE and CCVP studies.

Disclaimer and Due Credit:

This tutorial series is heavily based on CCIE Voice Home lab with Dynamips/VMware by Jayanm of Chicago, IL. Jaynam has obtained the following Cisco Certifications: CCIE (Voice) – CCVP – CCSP – CCNA – CQS (PIX,VPN,IDS) – VMWare Certified Professional.

I really appreciate the ground breaking research by Jaynam.

PC Preparation

  1. Install IPBlue on your workstation.  This part really shouldn’t require much of an explanation. You will need to download VTGO Lite. Here is the link.
