Charging information can be transmitted by ISDN in various formats and at different times. SwyxWare uses this information, which occurs almost exclusively during practical application, during the connection (AOC-D) or at the end of the connection (AOC-E). There are different variations for both of the above variants: The transmission of charging units or the transmission of charges as currency units. The type of information that is transmitted depends on the provider and the existing line. For more detailed information on this, contact your ISDN provider.

This type of charging information contains the number of charging units. The Deutsche Telekom generally uses this type of charge display. In order for the SwyxServer to be able to display the charges for a call in the telephony client or in the Call Detail Records, SwyxServer must know how expensive one charging unit is.
