Version 7.2 1115 Mediant 1000B Gateway & E-SBC
User's Manual 65. Configuration Parameters Reference
Parameter Description
 Expects to receive RFC 2833 packets with the same
payload type according to the RFC2833PayloadType
parameter.

Removes DTMF digits in transparent mode (as part
of the voice stream).
 [5] Info KOREA = Sends DTMF digits according to Korea
Telecom format.
Note:
 When out-of-band DTMF transfer is used ([1], [2], [3], or
[5]), the DTMFTransportType parameter is automatically
set to [0] (DTMF digits are erased from the RTP stream).
 If an ISDN phone user presses digits (e.g., for interactive
voice response / IVR applications such as retrieving
voice mail messages), ISDN Information messages
received by the device for each digit are sent in the voice
channel to the IP network as DTMF signals, according to
the settings of the parameter.
 For more information on DTMF transport, see
''Configuring DTMF Transport Types'' on page 201.
 You can also configure the parameter per specific calls,
using IP Profiles (IpProfile_FirstTxDtmfOption). To
configure IP Profiles, see ''Configuring IP Profiles'' on
page 423.
Second Tx DTMF Option
configure voip > gateway dtmf-supp-
service dtmf-and-dialing > second-
dtmf-option-type
[SecondTxDTMFOption]
Defines the second preferred transmit (Tx) DTMF
negotiation method. The first preferred method is configured
by the FirstTxDTMFOption parameter. For a description of
the optional values for the parameter, see the
FirstTxDTMFOption parameter above.
Note: You can also configure the parameter per specific
calls, using IP Profiles (IpProfile_SecondTxDtmfOption). To
configure IP Profiles, see ''Configuring IP Profiles'' on page
423.
configure voip > gateway dtmf-supp-
service dtmf-and-dialing > auto-dtmf-
mute
[DisableAutoDTMFMute]
Enables the automatic muting of DTMF digits when out-of-
band DTMF transmission is used.
 [0] = (Default) Automatic mute is used.
 [1] = No automatic mute of in-band DTMF.
When the parameter is set to 1, the DTMF transport type is
set according to the parameter DTMFTransportType and the
DTMF digits aren't muted if out-of-band DTMF mode is
selected (FirstTxDTMFOption set to 1, 2 or 3). This enables
the sending of DTMF digits in-band (transparent of RFC
2833) in addition to out-of-band DTMF messages.
Note: Usually this mode is not recommended.
