Parameter Description
■ The corresponding global parameter is IsTwoStageDial.
'FXO Double Answer'
fxo-double-answer
[TelProfile_
EnableFXODoubleAnswer]
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.
