c. Set the ini file parameter, DTMFTransportType to 2 (i.e., transparent).

Using INFO message according to Korea mode: DTMF digits are sent to the
remote side in INFO messages. To enable this mode:
a. Set the 'Declare RFC 2833 in SDP' parameter to No (RxDTMFOption = 0).
b. Set the 'First Tx DTMF Option' parameter to INFO Cisco (FirstTxDTMFOption =
3).
Note: DTMF digits are removed from the audio stream (and the 'DTMF Transport
Type' parameter is automatically set to Mute DTMF).
Notes:
• The device is always ready to receive DTMF packets over IP in all possible
transport modes: INFO messages, NOTIFY, and RFC 2833 (in proper payload
type) or as part of the audio stream.
• To exclude RFC 2833 Telephony event parameter from the device's SDP, set the
'Declare RFC 2833 in SDP' parameter to No.
• You can use the following parameters to configure DTMF digit handling:
√ FirstTxDTMFOption, SecondTxDTMFOption, RxDTMFOption,
RFC2833TxPayloadType, and RFC2833RxPayloadType
√ MGCPDTMFDetectionPoint, DTMFVolume, DTMFTransportType,
DTMFDigitLength, and DTMFInterDigitInterval
15.3.4 Configuring RFC 2833 Payload
The following procedure describes how to configure the RFC 2833 payload using the Web
interface:
 To configure RFC 2833 payload using the Web interface:
1. Open the RTP/RTCP Settings page (Configuration tab > VoIP menu > Media >
RTP/RTCP Settings). The relevant parameters are listed under the 'General Settings'
group, as shown below:
Figure 15-6: RFC 2833 Payload Parameters on RTP/RTCP Settings Page
2. Configure the following parameters:
• 'RTP Redundancy Depth' (RTPRedundancyDepth) - enables the device to
generate RFC 2198 redundant packets.
• For Gateway application only: 'Enable RTP Redundancy Negotiation'
(EnableRTPRedundancyNegotiation) - enables the device to include the RTP
redundancy dynamic payload type in the SDP, according to RFC 2198.
• 'RFC 2833 TX Payload Type' (RFC2833TxPayloadType) - defines the Tx RFC
2833 DTMF relay dynamic payload type.
• 'RFC 2833 RX Payload Type' (RFC2833RxPayloadType) - defines the Rx RFC
2833 DTMF relay dynamic payload type.
• 'RFC 2198 Payload Type' (RFC2198PayloadType) - defines the RTP redundancy
packet payload type according to RFC 2198.
