Parameter Description
'Disconnect Call on Busy Tone
Detection (CAS)'
configure voip > gateway
analog fxo-setting > disc-
on-bsy-tone-c
[DisconnectOnBusyTone]
Global parameter enabling call disconnection upon
detection of a busy tone.
You can also configure the feature per specific calls,
using Tel Profiles (TelProfile_
DisconnectOnBusyTone). For a detailed description
of the parameter and for configuring the feature in the
Tel Profiles table, see Configuring Tel Profiles.
Note:
■ The parameter is applicable only to the Gateway
application.
■ If the feature is configured for a specific Tel
Profile, the settings of the global parameter is
ignored for calls associated with the Tel Profile.
Polarity (Current) Reversal for Call Release (Analog Interfaces) Parameters
configure voip > interface
fxs-fxo > default-
linepolarity-state
[SetDefaultLinePolarityState]
Defines the FXO line polarity, required for DID
signaling.
■ [0] = Positive line polarity
■ [1] = Negative line polarity
■ [2] = (Default) Auto - The device detects the
polarity upon power-up or upon insertion of the RJ-
11 cable, and uses it as a reference polarity.
Typically, if the RJ-11 cabling is connected correctly
(without crossing, Tip to Tip, Ring to Ring), the Tip
line is positive compared to the Ring line. In this case,
set the parameter to 0. With this configuration, the
device assumes that the idle line polarity is Tip line
positive.
When the device receives a SIP INVITE, it checks
the FXO line polarity. If the polarity is "Reversed", it
skips this FXO line and goes to the next line.
Note:
■ For the parameter to take effect, a device reset is
required.
■ To take advantage of this new feature, configure
all FXO lines as a single Trunk Group with
ascending or descending channel select mode,
and configure routing rules to route incoming
INVITE messages to this Trunk Group.
■ The parameter is applicable only to FXO
interfaces.
'Enable Polarity Reversal'
configure voip > sip-
definition settings >
polarity-rvrsl
[EnableReversalPolarity]
Global parameter enabling the Line Polarity Reversal
feature for call release.
You can also configure the feature per specific calls,
using Tel Profiles (TelProfile_
EnableReversePolarity). For a detailed description of
the parameter and for configuring the feature in the Tel
Profiles table, see Configuring Tel Profiles.
