User's Manual
message contains the swapped numbers.

[0] Disable (default)

[1] Enable
Note: The corresponding global parameter is
SwapTEl2IPCalled&CallingNumbers.
Enables the Cut-Through feature, which allows phones connected to the
device's FXS ports to automatically receive IP calls (if there is no other
currently active call) even when in off-hook state (and no call is currently
active).

[0] Disable = Calls can only be received in on-hook state.

[1] CutThrough = (Enabled with tones) Calls can be
received in off-hook state. When the IP side ends the call,
the device can play a reorder tone to the Tel side for a
user-defined duration (configured by the
CutThroughTimeForReorderTone parameter). Once the
tone stops playing, the FXS phone is ready to automatically
answer another incoming IP call in off-hook state. A waiting
call is automatically answered by the device when the
current call is terminated (and if the EnableCallWaiting
parameter is configured to 1).

[2] CutThrough + Paging = (Enabled and no tones) Calls
can be received in off-hook state, but no tones are played
(before or after the call) in off-hook state. The option is
useful for paging calls, which provides a one-way voice
path from the paging phone to the paged phones (FXS
phones).
Note:

The parameter is applicable only to FXS interfaces.

The corresponding global parameter is CutThrough.
Enables the Polarity Reversal feature for call release.

[0] Disable (default)

[1] Enable = Enables polarity reversal:

FXS Interfaces: The device changes the line polarity on call
answer and then changes it back on call release.

FXO Interfaces: The device sends a SIP 200 OK response
when polarity reversal signal is detected (applicable only to
one-stage dialing) and releases a call when a second
polarity reversal signal is detected.
Note:

The parameter is applicable to FXS and FXO interfaces.

The corresponding global parameter is EnableReversalPolarity.
Enables call release upon detection of a Current Disconnect
signal.

[0] Disable (default)

[1] Enable = Enables the current disconnect service.

FXO Interfaces: The device releases a call when a current
disconnect signal is detected on its port.

FXS Interfaces: The device generates a 'Current
Disconnect Pulse' after the call is released from the IP side.
