I apologize for the delay in posting the next tutorial in the virtual voice lab but I ran into a problem communicating from the HQ router to the host Ubuntu server. I thought I was able to communicate from the HQ router to the host during the Headquarters build tutorial….but I was wrong.
This is the Frame-Relay WAN section of the Virtual Voice Lab. In this tutorial, you will learn how to connect Branch 1 and Branch 2 routers to the Headquarters router using frame-relay PVCs.

I just finished the video tutorial for the headquarters part of the virtual voice lab. This tutorial will basically walk you through adding all the devices for the headquarters location.

In the Virtual Voice lab series, I am using an Ubuntu Linux environment. To eliminate permissions issues, it is best that you run GNS3 as root.
Here are a couple issues I have experienced when running GNS3 as a normal user.
Not able to start dynamips.
Error msg: Can’t Connect to the hypervisor on port 7200
Not able to connect to a cloud object.
Error Msg: 206-unable to create Linux raw ethernet NIO
Error Msg: 206-unable to create Linux generic ethernet NIO
Error Msg: 206-unable to create UDP NIO
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.
Although this is the first tutorial following the Virtual Voice Lab Series introduction, the first tutorials were recorded and posted several months ago.
Install Call Manager 4.x with VMWare
How to install Call Manager 6.x in VMWare
These videos walked through the installation of Call Manager, but nothing more. Before I release a post on how to register phones to the virtual lab, we need to enable the services on the CUCM system and remove dependency on dns.
Is it possible to build a voice lab without actual hardware? The answer is yes and no. You can build a very good lab using GNS3 and VMWare but it is not possible to build a complete lab. The underlying emulation engine for GNS3 (dynamips) does not support digital signal processors (dsps) or voice cards.
Over the next few months, I will show you how to build a very good lab without any hardware. If you want a more complete lab, you will need to obtain at least one router with dsps and voice cards. I have a 2611XM router with DSPs, a vic-2fxs card, a vic-2fxo card and an ATA-186.
