This feature is a call drop standard for a FXS to determine whether or not to hang up the phone.
The RoIP will disconnect the call automatically to avoid keeping the line engaged if the detected
volume is below the Silence Detection Threshold or the time exceeds the Drop Silent Call
Timeout.
Silence Detection Threshold: When the detected audio is lower than the set-up threshold, the
connection will be hung up automatically.
Drop Silent Call Timeout: The system will hang up automatically when the detected audio is
lower then threshold and longer than timeout duration to avoid occupied lines.
Note: Improper values for above settings might cause unexpected automatic disconnection of a
call. Default values are recommended.
