Will VoIP Work Over VPN?

Remote workers working from the comfort of their home will likely use VPN or virtual private network to gain access to business resources. Since the company will not like any of their data to leak on to the internet and be broadcasted for all to see, it becomes essential for remote workers to use a secure internet connection.
The secure internet connection uses protocols to conceal information prior to sending it. Even though it is essential to protect the data being sent, it is not as important to provide the same amount of security to VoIP connection via a VPN connection.

Why Do Remote Workers Need to Utilize VoiP Connections via VPN Connections?

The remote workers uses their home office as a place to access the company’s website and any given resources they provide them. In doing so, their home turns into an extension of the company’s LAN. In order to limit NAT problems, they need to use VoIP over VPN, which means it will work.
For instance, remote workers connect to a hosted VoIP service, their VPN meant to connect to their office will not tunnel voice. Instead, it will connect directly through the router of their home to the VoISP over their internet connection. To make voice calls using VoIP over VPN improves voice quality needed to make a call to the office or to a client.

How Voice Quality Improves?

Traffic for VoIP improves voice quality because it uses UDP to decrease latency while TCP works to ensure that all the packets arrive at their destination in order. However, one holdup in the delivery can cause the entire stream to stall. In the event of a delay in the packets getting to their destination, you need to burst bandwidth to assist the package find its way to the destination.
To assist it in its journey to the correct destination, it will detect the fault, and then retransmit the data to fill the hole. This in return will improve voice quality, meaning it is a good idea to provide remote workers with VoIP over VPN.
It may increase the voice quality by 500 kbps, assuming you have a good network. VoIP over VPN will do more than increase voice quality, but it will encrypt the call, which several VoIP protocol have failed to do. Another benefit is that if you have sufficient amounts of burst bandwidth, you can easily have about twelve remote users.
Out of the 2 Mbps pipe, they will be consuming below 1 Mbps, leaving you with an extra 1 Mbps burst capability to use in case any packets become lost on their way. If the remote workers spend their time researching on the internet, transferring files, and more, the numbers will need to be adjusted.
If you have remote workers working from their home or any other destination, you should incorporate VoIP over VPN to improve voice quality. This will be the best move you would make in a long time.
