can be difficult to get them to work reliably together, and in many cases it does more harm than good. You run

into a situation where maybe five or 10 percent of calls are improved quite a bit, but the remaining 90 percent

actually get a little worse. Which is a better trade-off?

In the end, most VoIP systems installed as end-user customer premise equipment, (including Allworx) employ

only LECs, not NECs. The reasons are both technical and economic. NECs require significantly more

processing power than LECs and are historically very expensive to implement on several channels at a time.
