Call Logging

Call logging, as defined by Wikipedia:

Call logging is the process of collecting phone call data, analysing this data, and then reporting on the telephone network’s cost, performance, capacity and quality of service (QoS). It should not be confused with telephone tapping or call recording. The former refers to listening to calls, while the latter is about recording conversations.

Collecting data

Data is collected from a PBX and is referred to as CDR data (Call Detail Record). Almost all PBXs provide a way to output CDR data. On older, traditional PBXs, this is usually through a serial port. On newer models, an Ethernet connection is normally used. The CDRs are delivered via the appropriate method to a PC running the call logger software. Some PBX manufacturers provide their own basic call logging software but there are many other third party software packages available.

Call logging software

The job of the call logging software is to interpret the raw CDR data and allow the user to produce graphical reports. Call logging software packages differ in the sizes of PBX systems that they can support (from hundreds of extensions to hundreds of thousands of extensions). They also differ in reporting capability and support for specialised PBX features.

In general terms, call logging reports can highlight such areas as:

  • Cost Control – cost of calls, cost of trunk lines, costs by department or individual extension, number of unused extensions, etc. Call logging software can also discover instances of Telephone fraud.
  • Performance Management – looks at how long it is taking an organisation to answer phone calls by operator, department or extension and demonstrates whether they meet acceptable target levels for that organisation.
  • Capacity Management – judges whether the system is being over or under utilised. It examines trunk usage and call patterns that show where extra capacity is required or where cost savings can be achieved.
  • QoS Reporting – modern VoIP PBXs are able to output quality of service data in addition to standard CDRs. An up to date call logging package should be able to include this data along with its other reports to help monitor and improve system performance.
