<Detect_CPC_3_> Choose yes to enable or choose no to disable this feature.
CPC is a brief removal of tip-and-ring voltage. If enabled, the
ATA will disconnect both call legs when this signal is detected
during a gateway call.
Default setting: yes
<Detect_Polarity_Reversal_3_> 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
<Detect_PSTN_Long_Silence_3_> 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
<Detect_VoIP_Long_Silence_3_> 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
<PSTN_Long_Silence_Duration_3_> 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
<VoIP_Long_Silence_Duration_3_> 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
<PSTN_Silence_Threshold_3_> 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
