Siemens Hicom 150 E Office - Silent Reversal at Start and End of Call

7.12 Features for Call Detail Recording
7.12.1 Silent Reversal at Start and End of Call
Definition
In many countries, a "silent reversal" is used on loop start trunks to record the start and end of an
outgoing call. These criteria are used for time recording within central call detail recording. This is
especially necessary when an exact settlement of call charges is required (e.g. hotel).
The feature can be set for each circuit.
