Consider Separating Your Data and VoIP Networks

Posted by Mark Greim on Jun 8, 2012 12:50:00 PM

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 voice and data 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.

With 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 (80k 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 screaming of 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.

Got VoIP? You Need VoIP QoS!

Posted by Mark Greim on Apr 6, 2010 9:49:00 AM

Consumers have long searched for ways to reduce their household expenditures.  Many are ditching their land line phones in favor of their cell phones or have turned to an inexpensive Voice over IP provider. Such movement has been great for the competitive marketplace, but has also built a perception that by going to a VoIP application you are sacrificing the quality of your phone call. 

For most businesses, going wireless only or converting to a VoIP provider who doesn’t deploy a quality of service technology are simply not good alternatives.  Despite the fact that wireless has introduced us to “dropped calls” and certain VoIP carriers have left us underwhelmed by “voice in a cave” quality, it doesn’t mean that this is an acceptable standard in the business marketplace.  You and your customers deserve to have the highest class of a communication experience. 

There are several root causes of a poor voice experience with some VoIP carriers, from inadequate bandwidth and latency, to lack of the proper technology applied.  These can be avoided by careful screening and selection of your VoIP provider.  Here are some questions for you to ask as you evaluate making the change:

1.     Does the provider evaluate your current bandwidth utilization and your expected call volume?

2.     Does the provider deliver a router or bridge device preprogrammed with a quality of service (VoIP QoS) software?

3.     Does the provider conduct your service installation on-site?

4.     Does the provider configure your phones to how you do business? 

The VoIP QoS software is a must for these applications.  It simply prioritizes the movement of voice packets over the internet connection, keeping the data packets flowing, but not interrupting the voice transmission.  The other questions above will give you a feeling as to how the company conducts business – preprogrammed drop ship or customized to their customers’ needs. 

There are many benefits for business to move to a VoIP application, from cost savings to advanced communication features for your business.  Choosing the right provider with an eye on quality will increase your satisfaction and effective utilization of the service.
