Consider Separating Your Data and VoIP Networks

Posted by Mark Greim on Jul 15, 2019 9:18:49 AM

With business internet usage continuing to increase, contention for bandwidth between your data and VoIP activity can create problems.  Yes, the convergence buzzword has been replaced with contention!

Why is this happening?  Businesses are evolving faster than the ability for suppliers of bandwidth to keep up with demand.  More are using cloud computing applications, using the internet to move data to a host server rather than to servers on their local area networks.  On-line data backup is another such application.  General use of the internet continues to accelerate, both for personal and business purposes.  With the sky-rocket adoption rate of smart phones, the lines between business and personal have blurred, and office internet usage is following suit.  Social media is not only a personal outlet, but a business tool and resource.  Buying practices have shifted toward internet research and ecommerce, and marketing activity has followed. Separate Data and Voice Networks

I’m looking at my personal browser.  On a daily basis, my browser auto-opens tabs for three social media sites, four cloud applications, news, and Google.  Each application is actively worked throughout the day.  This is becoming the norm, and it requires a lot of bandwidth to perform efficiently.

What is the impact on VoIP applications?  When a company uses a hosted VoIP service, voice packets travel over the same internet connection as the data packets.  Good VoIP companies will provide a quality of service device or program your router to prioritize voice packets over data to ensure that your calls remain clear and free from interruption.  However, if the internet connection is highly saturated with activity, even the best QoS routines will be compromised.  Phone conversations can experience poor voice quality and phones can lose their registration and go off-line.

What can be done?  Where available, you should look at your internet provider’s capability to add bandwidth to the circuit or change to a provider who has the ability to grow with your needs.  Depending upon your internet usage and needs, you still may have occasional contention between your voice and data traffic.  Again, make sure your VoIP provider has the capabilities to implement QoS on your network.  However, an alternative may be to separate your voice and data network.

Finally_Make_the_Move_to_VoIP-3With a separate voice and data network, your calls and phones will no longer be impacted by your data usage.  Many VoIP phones have two ports on the back which allow for a computer to share an Ethernet cable to the network.  The phones and computers can still share an Ethernet connection to the servers, but they will simply be directed out disparate internet connections.  This can be accomplished by setting up a vLan on your switch or by simply assigning the phones separate IP addresses and route them out the new internet connection.  Your network manager or your hosted VoIP provider should be able to assist you with this programming. 

Finally, voice calls do not require much bandwidth (80 kb/s non-compressed).   Dependent upon your concurrent call maximum, your alternative connection may not be required to be very large.

Capture some statistics on your network usage.  Compare this with the anecdotal complaints from your employees about internet speeds and VoIP call quality and then investigate your options for more bandwidth and/or disparate connections for voice and data.
