Mediant 1000B Gateway & E-SBC
Parameter Description
setting > guard-time-btwn-calls
[GuardTimeBetweenCalls]
The valid range is 0 to 10. The default is 1.
Note: Occasionally, after a call ends and on-hook is applied, a
delay is required before placing a new call (and performing off-
hook). This is necessary to prevent incorrect hook-flash
detection or other glare phenomena.
FXO Double Answer
configure voip > gateway analog fxo-
setting > fxo-dbl-ans
[EnableFXODoubleAnswer]
Global parameter enabling the FXO Double Answer feature,
which rejects (disconnects) incoming Tel-to-
IP collect calls and
signals (informs) this call denial to the PSTN..
You can also configure the functionality per specific calls,
using Tel Profiles (TelProfile_EnableFXODoubleAnswer). For
a detailed description of the parameter and for configuring the
functionality in the Tel Profiles table, see ''Configuring Tel
Profiles'' on page 459.
Note: If the functionality is configured for a specific Tel Profile,
the settings of the global parameter is ignored for calls
associated with the Tel Profile.
FXO Ring Timeout
configure voip > gateway analog fxo-
setting > fxo-ring-timeout
[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.
This feature is useful for telephony services that employ
constant ringing (i.e., 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 second on, 4
second 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 can be configured for a Tel Profile.
[EnablePulseDialGeneration] Enables pulse dialing generation to the analog side (FXO)
when dialing is received from the IP side.
 [0] Disable = (Default) Device generates DTMF signals to
the FXO side.
 [1] Enable = Device generates pulse dialing to the FXO
side.
Note: For the parameter to take effect, a device reset is
required.
[PulseDialGenerationBreakTime] Defines the duration of the Break connection (off-hook) for
FXO pulse dial generation.
The valid value range is 20 to 120 (in msec). The default is 60.
Note: For the parameter to take effect, a device reset is
required.
[PulseDialGenerationMakeTime] Defines the duration of the Make connection (on-hook) for
FXO pulse dial generation.
