User's Manual 69. Configuration Parameters Reference
Parameter Description
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 471.
Note:
 The parameter is applicable only to FXS and FXO
interfaces.
 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.
 [0] = DTMF event is reported at the end of a detected
DTMF digit.
 [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 438.
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.
First Tx DTMF Option
configure voip > gateway dtmf-supp-
service dtmf-and-dialing > first-dtmf-
option-type
[FirstTxDTMFOption]
Defines the first preferred transmit (Tx) DTMF negotiation
method.
 [0] Not Supported = (Default) No negotiation. DTMF
digits are sent according to the parameters
DTMFTransportType and RFC2833PayloadType. The
RFC 2833 payload type is according to the
RFC2833PayloadType parameter for transmit and
receive.
 [1] Info NORTEL = Sends DTMF digits according to IETF
Internet-Draft draft-choudhuri-sip-info-digit-00.
 [2] NOTIFY = Sends DTMF digits according to IETF
Internet-Draft draft-mahy-sipping-signaled-digits-01.
 [3] Info Cisco = Sends DTMF digits according to Cisco
format.
 [4] RFC 2833 = The device handles DTMF as follows:

Negotiates RFC 2833 payload type using local and
remote SDPs.
 Sends DTMF packets using RFC 2833 payload type
