Generally, with any properly installed business-oriented VoIP solution, you will experience call quality equal to or better than a traditional phone call.
However, VoIP call quality can easily be affected by network congestion and delays. Most VoIP solutions have no answer for this problem.
The StarWatch service from Star2Star measures the quality of the network and adjusts call parameters to assure the best possible quality.
In addition, StarWatch can detect a degrading local area or wide area (Internet) connection and alert you to this problem along with recommended solutions.
Star2Star's unique integrated combination of proprietary hardware, monitoring, and central routing service means we do the best possible job of assuring call quality and reliability for our customers.
