DTMF Users can choose different ringtones.
This parameter specifies the mechanism to transmit
DTMF digits. There are 3 supported modes:
• In audio, which means DTMF is combined in the
audio signal (not very reliable with low-bit-rate
codecs);
• RTP (RFC2833), which means to specify DTMF
with RTP packet. Users could know the packet is
DTMF in the RTP header as well as the type of
DTMF;
• SIP INFO. Use SIP info to carry DTMF. The defect
of this mode is that it's easily to cause desynchrony
of DTMF and media packet for the reason the SIP
and RTP are transmitted respectively. The default
setting is "RFC2833".
