All companies have call centers, even if they not called by that name.
Call Explorer sends graphs to web pages. These can show in real time calls made, received and even lost calls, shown in red.
It is easy so see how the number of calls increase during the lunch hour, but unfortunately so do the lost calls.
All is not lost, Call Explorer can also send a report of the numbers of the incoming calls not answered, so they can quickly be called back.
