Call Records
Important information about call records from Mark van der Hoek (Senior RF engineer) and Professor R.C. Levine. First, from Mark.
Call records do contain the information on the FIRST site to handle the call, and the LAST site. To be more precise, most sites are divided into SECTORS, each of which serves a different geographical area. The first and last serving site AND sector is recorded on the billing record by the SWITCH. Switches are the central computer that controls the network, essentially. It is the switch that records the call
information.
