Voice over internet protocol (VoIP) revolutionized business calling. Any device with a broadband connection can make calls anywhere and improve productivity. Additionally, VoIP is easy to update, so its implementation is scalable.
And no one complains about the cost. Calls made from any phone connected to the internet actually means a cost reduction. But some people do complain about poor VoIP call quality.
See, VoIP still comes with its own, sometimes complex, problems. The good news is most problems are easily fixed with the right troubleshooting steps.
