Parameter
Mediant 800 Gateway & E-SBC | User's Manual
Description
Note: You can also configure the parameter per
specific calls, using IP Profiles (IpProfile_
SecondTxDtmfOption). To configure IP Profiles,
see Configuring IP Profiles.
Enables the device to simultaneously send DTMF
tones (signals) in SIP messages such as INFO
messages (out-of-band) and in RTP media streams
(in-band) with a special payload type (as defined in
RFC 2833), when the FirstTxDTMFOption
parameter is configured to 4. The parameter must
be configured to the method for transporting DTMF
digits over the IP network to the remote endpoint.
For more information on DTMF transport, see
Configuring DTMF Transport
■ [0] = (Default) DTMF is sent according to
FirstTxDTMFOption.
■ [1] = Nortel
■ [2] = Cisco
■ [3] = Threecom
■ [4] = Korea
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.
Enables the Digit Delivery feature whereby DTMF
digits are sent to the destination IP address after
the Tel-to-IP call is answered.
■ [0] Disable (default)
■ [1] Enable = Enable digit delivery to IP.
To enable this feature, modify the called number to
include at least one 'p' character. The device uses
the digits before the 'p' character in the initial
INVITE message. After the call is answered, the
device waits for the required time (number of 'p'
multiplied by 1.5 seconds), and then sends the rest
of the DTMF digits using the method chosen (in-
band or out-of-band).
