DTMF TYPE
DTMF TYPE is used for telephone signaling over the line in the voice frequency band
to the call switching center. DTMF means that two groups of tone with different
frequencies are united into 16 kinds of dial tone. The telecommunication station,
switch or the phone service such as 1860 identify these special tones through DSP
analysis to confirm the keys dialed by user. There are two DTMF types: Inband DTMF
type and Outband DTMF type.
Inband DTMF type transfers these special dial tones together with the speech tone
without doing any special processing to them. So there is not any type as to Inband
DTMF.
Outband DTMF type transfers these special dial tones by some special method to
confirm its correctness. The special method is the so called protocol such as
RFC2833 and SIP information.

DTMF Payload Type
DTMF Payload Type is used to carry telephony tones and telephony signals. By using
a distinct dynamic RTP payload type in the same RTP stream as the media, it is
possible to carry DTMF tones, fax-related tones, standard subscriber line tones,
country-specific tones and trunk events.
