Solarwinds VoIP and Network Quality Manager is a VoIP analytics and monitoring tool.
It is best suited when you want to have different operating systems on your laptop or desktop. You can easily switch between operating systems without the need to uninstall one. In another scenario, if you expect some application to damage your device, it would be best to run the application on the VM such that the damage can only be done to the virtual machine. It is less appropriate when time synchronization is very important. At times the VMs run their own times differently from the host time and this may cause some losses if what you doing is critical. Another important thing to take note of is the licensing of the application you want to run your VM. Some licenses do not allow the applications to be run on virtual servers so it is not appropriate to use the VM at this time.

It is best suited for managing and monitoring homogenous networks where the design is similar across the board. The most obvious use case is to make sure the correct network quality of service is being maintained to ensure voice call quality in a converged networked. It would be less suited/necessary if the voice and data networks were segmented from each other.

I have had issues in the past when it has come to resizing VM disk storage. The issue is entirely detailed here: https://www.virtualbox.org/ticket/9103 -- the problem was caused because of having existing snapshots (which error message output was not detailing). I haven't had to deal with the issue due to my dynamic disk sizes not being small from the start anymore (this is mostly an issue for my Windows VMs where the base disk may need significant size for the OS). It looks like, for a resize, that a merge of all snapshots has to occur first -- one user on that list details a workaround to maintain snapshots by cloning the VM. (Note: 5.2 was just released a few weeks ago, and looks like it should prevent the problem happening in the future by properly informing users that it isn't possible with snapshots).
Certain scenarios, like resizing disks, required dropping into a terminal as there were no options to previously do so via the GUI. According to some recent posts, I've seen that v5.2 has added disk management stuff like that to the GUI (or will be adding it). I'm comfortable with dropping into the terminal, but in a teaching scenario or when evaluating the learnability of the tools, it complicates things.

The impact on SolarWinds performance itself of configuring a large number of IPSLA operations for monitoring can be difficult to predict. It would be beneficial to have some tools that could warn or predict the results of doing so.
Additional background information on the use case for each SLA operation type would be helpful to the user who may not be an expert in the field. The Server and Application Monitor product provides this benefit for application component monitoring.
The tool should be engineered to allow repeated SLA node discovery for any and all nodes in the Orion Platform database.

I love using the Graphical User Interface. The VirtualBox Manager is very easy to understand and use. You can quickly create, configure and manage all your virtual machines in one window. It makes operating virtual machines easy and simple. When using VBoxManage it gives the user comprehensive control over VirtualBox so that you can use automation and scripting at the command-line interface

VirutalBox is very similar to using Vmware with the slight difference in appearance and what might be considered a less polished look. However, what it lacks in polish and looks it makes up for in functionality, easy of use and the wide range of operating systems and features it supports without the need of buying the full professional edition

Our VOIP system is from Cisco, so they suggested their Packet Tracer to help with managing our quality of service. We found it to be an extremely technical tool much better aligned with diagnosing a detailed issue rather than helping monitor and manage the VOIP traffic as Solarwinds does.

The only problem I have found is that the deployment is dependent and intrinsically linked to the Host OS. This is different from bare metal solutions which remove that dependency on a Host OS. The latter is more reliable and removes a layer of potential failure.

Minimal-to-no support needed from the DevOps team.
Provides a direct and an easy way to access multiple VMs inside the same machines which enables performing various testing and QA tasks without the need to switch hardware.
Automatic provisioning using tools (esp. Vagrant) which enables developing a base image once, and allows for exporting/importing anywhere across the developers team.
Very cost-effective (no fees or monthly subscriptions).

VNQM has enabled our network engineers to see network quality issues from the end user perspective and thus be more proactive.
The call records searching capability is very user friendly and has made it easy for VoIP engineers to troubleshoot call issues from a single pane of glass.
We were able to implement SLA monitoring by leveraging an existing feature of our Cisco routers. No additional investment was required.
