Description
Choose yes to enable or choose no to disable this feature.
If enabled, the ATA will disconnect both call legs when this
signal is detected during a gateway call. If it is a PSTN
gateway call, the first polarity reversal is ignored and the
second one triggers the disconnection. For VoIP gateway
call, the first polarity reversal triggers the disconnection.
Default setting: yes
Choose yes to enable or choose no to disable this feature.
If enabled, the ATA will disconnect both call legs when the
PSTN side has no voice activity for a duration longer than
the length specified in the Long Silence Duration
parameter during a gateway call.
Default setting: no
Choose yes to enable or choose no to disable this feature.
If enabled, the ATA will disconnect both call legs when the
VoIP side has no voice activity for a duration longer than
the length specified in the Long Silence Duration
parameter during a gateway call.
Default setting: no
This value is minimum length of PSTN silence (or
inactivity) in seconds to trigger a gateway call
disconnection if Detect Long Silence is enabled.
Default setting: 30
This value is minimum length of VoIP silence (or inactivity)
in seconds to trigger a gateway call disconnection if
Detect Long Silence is enabled.
Default setting: 30
This parameter adjusts the sensitivity of PSTN silence
detection. Choose from {very low, low, medium, high, very
high}. The higher the setting, the easier to detect silence
and hence easier to trigger a disconnection.
Default setting: medium
Specify the minimum duration of a low tip-and-ring
voltage (below 1V) for the Gateway to recognize it as a
CPC signal or PSTN line removal.
Default setting: 0.2
