Many companies and organizations are using office switching systems (PBX, PABX) to control their telecommunications. Call bills are usually the largest part of all telecommunication expenses.
While International and long-distance calls costs are going down, the bills are still considerable. Call accounting can help you reduce these bills by motivating employees to make significantly less non-business calls.
Modern switching systems can provide useful information to help you manage these expenses. This function is typically called SMDR (Station Message Detail Recording) or CDR (Call Detail Recording). The system outputs call records in plain text via serial port (or Telnet network connection). Call record always include basic information about the call (extension number, trunk id, dialed number, call starting time and duration). Some systems can output extra information (account code, call type, Caller ID information for incoming calls, etc.).
To collect and process these vast amounts of information you would need a call accounting software package like PBX Call Tarifficator. It can work with any PBX system that provides SMDR/CDR output. Please contact your PBX installer to check if your system can do it.
