ATA Voice Field Reference Line page B Detect Polarity Reversal If enabled, SPA will disconnect both call legs when this signal is detected during a gateway call. If it is a PSTN gateway call, the 1st polarity reversal is ignored and the 2nd one triggers the disconnection. For VoIP gateway call, the 1st polarity reversal triggers the disconnection. Detect PSTN Long Silence The default is yes. If enabled, SPA will disconnect both call legs when the PSTN side has no voice activity for a duration longer than the length specified in the PSTN Long Silence Duration parameter during a gateway call. Detect VoIP Long Silence The default is yes. If enabled, SPA will disconnect both call legs when the VoIP side has no voice activity for a duration longer than the length specified in the VoIP Long Silence Duration parameter during a gateway call. The default is no. PSTN Long Silence This value is minimum length of PSTN silence (or inactivity) Duration in seconds to trigger a gateway call disconnection if Detect PSTN Long Silence is yes. VoIP Long Silence Duration The default is 30. This value is minimum length of VoIP silence (or inactivity) in seconds to trigger a gateway call disconnection if Detect VoIP Long Silence is yes. PSTN Silence Threshold The default is 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. Min CPC Duration Detect Disconnect Tone The default is 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. The default is 0.2. If enabled, SPA will disconnect both call legs when it detects the disconnect tone from the PSTN side during a gateway call. Disconnect tone is specified in the Disconnect Tone parameter, which depends on the region of the PSTN service. The default is yes. Cisco Small Business ATA Administration Guide 186

Detect Polarity
Reversal
If enabled, SPA will disconnect both call legs when this
signal is detected during a gateway call. If it is a PSTN
gateway call, the 1st polarity reversal is ignored and the
2
nd
one triggers the disconnection. For VoIP gateway call,
the 1
st
polarity reversal triggers the disconnection.
The default is
yes
.
Detect PSTN Long
Silence
If enabled, SPA will disconnect both call legs when the
PSTN side has no voice activity for a duration longer than
the length specified in the PSTN Long Silence Duration
parameter during a gateway call.
The default is
yes
.
Detect VoIP Long
Silence
I
f enabled, SPA will disconnect both call legs when the
VoIP side has no voice activity for a duration longer than
the length specified in the VoIP Long Silence Duration
parameter during a gateway call.
The default is
no
.
PSTN Long Silence
Duration
This value is minimum length of PSTN silence (or inactivity)
in seconds to trigger a gateway call disconnection if
Detect PSTN Long Silence is yes.
The default is
30
.
VoIP Long Silence
Duration
This value is minimum length of VoIP silence (or inactivity)
in seconds to trigger a gateway call disconnection if
Detect VoIP Long Silence is yes.
The default is
30
.
PSTN Silence
Threshold
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.
The default is
medium
.
Min CPC Duration
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. The default is
0.2
.
Detect Disconnect
Tone
If enabled, SPA will disconnect both call legs when it
detects the disconnect tone from the PSTN side during a
gateway call. Disconnect tone is specified in the
Disconnect Tone
parameter, which depends on the region
of the PSTN service.
The default is
yes
.
