enable_info_bas
ed_dtmf
This parameter specifies whether the
voice client transmits DTMF digits in
INFO method SIP messages rather than
inband or via RFC 2833 signaling. When
enabled, this parameter takes
precedence over the enable_rfc2833
parameter. The content type for the
INFO messages is controlled by the
content_type_for_info parameter. The
default value is “no” (disabled).

events. The two supported values for
this parameter are
“audio/telephone-event” and

annexb_in_sdp Specifies the appearance of the annexb
parameter in the SDP during
negotiation of G729 as a codec as
follows. If enable_vad is set to
Yes/True/1, then the string a=fmtp:18
annexb=yes is added to the SDP. When
set to No/False/0, then the string
a=fmtp:18 annexb=no is added to the
SDP. If the SDP codec list does not
include G.729 or this parameter is set
to False/No/0, then the annexb text is
not added to the SDP under any
circumstances. The default is
No/False/0.
