Features for Call Detail Recording

Silent Reversal at Start and End of Call 
 
Implementing features, see also Manager E Silent Reversal at Start and End of Call

Definition  
Many countries use silent reversal to mark the beginning and end of outgoing calls on loop start trunks. These criteria are used for time recording within central call detail recording. This is particularly important when exact tracking of call charges is required (as in a hotel).
The feature can be configured per circuit.
