Version 7.2 1037 Mediant 1000B Gateway & E-SBC
User's Manual 62. Configuration Parameters Reference
Parameter Description
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
according to the payload type in the received SDP.

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 191.
 You can also configure the parameter per specific calls,
using IP Profiles (IpProfile_FirstTxDtmfOption). To
configure IP Profiles, see ''Configuring IP Profiles'' on
page 393.
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
393.
