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.

In a previous tutorial, you learned how to install Call Manager 4.x in vmware. Installing CUCM 6.x in VMWare is much easier. Cisco did a great job with CUCM 6.x in terms of allowing you to install the software in a virtual machine without needing to hack the system.

In Part 1 of the Internet lab tutorial, we created a virtual "internet" using gns3. We built the infrastructure and configured a router to represent "The Internet" (ISP). This time, you will add switches and configure the internet routers at each customer site. Other tutorials will follow that use these two tutorials as a foundation.

We all know dynamips is a great tool for creating virtual networks and testing router configurations.  However, I can never seem to really understand a concept unless I use it in a "real" scenario. I will show you how  I have started using dynamips as my personal internet router.

In a previous tutorial, I showed you how to create a vmware session with easyvmx and vmware player. This time, I will show you how to take this one step further … installing vmware tools. VMware tools enhances the vmware experience with better graphics and device support. VMware player does not come with the tools.

Installing Call Manager version 4.x has been quite a task. All the tutorials I had been following until recently made reference to OS upgrade version 2000.2.6. However, this version no longer available for download on Cisco.com. I tried to follow the tutorials for version 2000.4.4a but ran into several issues … the registry hack did not work and version 2000.4.4a did not include MS Java … just to name a few. The following tutorials will walk you through every step to successfully install Callmanager with VMWare Player.

This tutorial demonstrates creating a virtual frame-relay network using Dynamips.

This tutorial will show you how to connect three routers together with  a virtual hub within the dynamips / dynagen framework.

When using dynagen and dynamips, the application used for console access is normally basic telnet. Personally, I do not like the windows telnet application at all. It does not allow logging or the ability to maximize the window.
