The Top Five Myths About VoIP Call Quality, Part Five: The Sniffer Will Fix It

September 28th, 2016

If there’s one lesson you can take away from our recent series on the top VoIP call quality myths, it’s that you can’t take a cavalier approach to VoIP troubleshooting and expect strong results.

September 15th, 2016

It is estimated that Southwest lost between $5 million and $10 million in ticket sales during this time period. Read more »

Many network professionals, in other words, fail to take into account the fact that VoIP issues can take place even over a LAN network. They carry on thinking everything is in working order, when in fact there are many issues taking place behind the scenes that are subjecting users to a bad call experience. The problem lies in making assumptions about the state of your network instead of taking a scientific approach and examining how the network is actually performing. Read more »

June 2nd, 2016
