It is simple. Most call accounting systems are installed in server rooms or wiring closets. These are places where the people, who need the call accounting information the most, do not have easy access to. Therefore, either MIS has to print the reports for them or they have to physically go to the server room / wiring closet to print the reports out. However, some modern call accounting systems do provide a LAN version to print reports, but such systems do not allow the complete setup / modification via LAN.
On the other hand, our Call Accounting Mate system allows ALL functions to be accessed using a browser. No extra components need to be installed to access the system. Complete installation / administration of Call Accounting Mate is accomplished using a browser.
