Mediant 1000B Gateway & E-SBC
Parameter Description
Note:
ï‚§ Digital interfaces: The device can interwork DTMF
HookFlashCode to SIP INFO messages with Hook Flash
indication.
ï‚§ FXO interfaces support only the receipt of RFC 2833
Hook-Flash signals and INFO [1] type.
ï‚§ FXS interfaces send Hook-Flash signals only if the
EnableHold parameter is set to 0.
Min. Flash-Hook Detection Period
configure voip > interface fxs-fxo >
min-flash-hook-time
[MinFlashHookTime]
Defines the minimum time (in msec) for detection of a hook-
flash event. Detection is guaranteed for hook-flash periods
of at least 60 msec (when setting the minimum time to 25).
Hook-flash signals that last a shorter period of time are
ignored.
The valid range is 25 to 300. The default is 300.
Note:
ï‚§ The parameter is applicable only to FXS interfaces.
ï‚§ It's recommended to reduce the detection time by 50
msec from the desired value. For example, if you want to
set the value to 200 msec, then enter 150 msec (i.e., 200
minus 50).
Max. Flash-Hook Detection Period
configure voip > interface fxs-fxo >
flash-hook-period
[FlashHookPeriod]
Global parameter defining the hook-flash period (in msec)
for Tel and IP sides.
You can also configure the functionality per specific calls,
using Tel Profiles (TelProfile_FlashHookPeriod). For a
detailed description of the parameter and for configuring the
functionality in the Tel Profiles table, see Configuring Tel
Profiles on page 428.
Note:
ï‚§ The parameter is applicable only to FXS and FXO
interfaces.
ï‚§ 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.
DTMF Parameters
notify-on-sig-end
[MGCPDTMFDetectionPoint]
Determines when the detection of DTMF events is notified.
ï‚§ [0] = DTMF event is reported at the end of a detected
DTMF digit.
ï‚§ [1] = (Default) DTMF event is reported at the start of a
detected DTMF digit.
Declare RFC 2833 in SDP
configure voip > gateway dtmf-supp-
service dtmf-and-dialing > rfc-2833-in-
sdp
[RxDTMFOption]
Global parameter that enables the device to declare the
RFC 2833 'telephony-event' parameter in the SDP. You can
also configure this functionality per specific calls, using IP
Profiles (IpProfile_RxDTMFOption). For a detailed
description of the parameter and for configuring this
functionality in the IP Profiles table, see ''Configuring IP
Profiles'' on page 393.
Note: If this functionality is configured for a specific IP
Profile, the settings of this global parameter is ignored for
calls associated with the IP Profile.
