
[1] Yes = (Default) Two-stage dialing. In this mode, the
device seizes one of the PSTN/PBX lines without performing
any dialing, connects the remote IP user to the PSTN/PBX
and all further signaling (dialing and Call Progress Tones) is
performed directly with the PBX without the device's
intervention.
Note:

The parameter is applicable only to FXO interfaces.

The corresponding global parameter is IsTwoStageDial.
Enables the FXO Double Answer feature, which rejects
(disconnects) incoming (FXO) Tel-to-IP collect calls and signals
(informs) this call denial to the PSTN.

[0] Disable (default)

[1] Enable
Note:

The parameter is applicable only to FXO interfaces.

The corresponding global parameter is
EnableFXODoubleAnswer.
Defines the delay (in msec) before the device generates a SIP
INVITE (call) to the IP side upon detection of a RING_START
event from the Tel (FXO) side. This occurs instead of waiting
for a RING_END event.
The feature is useful for telephony services that employ
constant ringing (i.e., when no RING_END is sent). For
example, Ringdown circuit is a service that sends a constant
ringing current over the line, instead of cadence-based 2
seconds on, 4 seconds off. For example, when a telephone
goes off-hook, a phone at the other end instantly rings.
If a RING_END event is received before the timeout expires,
the device does not initiate a call and ignores the detected ring.
The device ignores RING_END events detected after the
timeout expires.
The valid value range is 0 to 50 (msec), in steps of 100-msec.
For example, a value of 50 represents 5 sec. The default value
is 0 (i.e., standard ring operation - the FXO interface sends an
INVITE upon receipt of the RING_END event).
Note:

The parameter is applicable only to FXO interfaces.

If the parameter is configured for a specific FXO port, Caller
ID detection does not occur and the RingBeforeCallerID and
FXONumberOfRings parameters do not affect the outgoing
INVITE for that FXO port.

The corresponding global parameter is FXORingTimeout.
Defines the hook-flash period (in msec) for Tel and IP sides.
For the IP side, it defines the hook-flash period reported to the
IP. For the analog side, it defines the following:

FXS interfaces:

Maximum hook-flash detection period. A longer signal is
considered an off-hook or on-hook event.

Hook-flash generation period upon detection of a SIP
