Tel Profile Parameter Global Parameter
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.
FXO Double Answer
fxo-double-answer
[TelProfile_EnableFXODoubleAnsw
er]
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.
FXO Ring Timeout
fxo-ring-timeout
[TelProfile_FXORingTimeout]
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.
Flash Hook Period
flash-hook-period
[TelProfile_FlashHookPeriod]
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
INFO message containing a hook-flash signal.

FXO interfaces: Hook-flash generation period.
