ONT Product Information Guide
enable_rfc2833 Indicates whether voice activity
detection is enabled for voice
encoding. In order for DTMF tones to
be encoded in RFC 2833 packets,
there must be SDP negotiation and
agreement at both ends of the
bearer channel. The ONT or MDU will
offer RFC 2833 or include it in an SDP
response only if the enable_rfc2833
is set to yes. This is a string
containing a value of “yes” or “no.”.
The default value is “yes.”
When set to ‘far_end_symmetry”,
during SDP negotiations of the RFC
2833 payload type, the ONT offers
the configured
dynamic_codec_payload_map_entry
value for RFC 2833. However, if the
ONT receives an answer to an offer
with a different payload type, the
ONT uses that payload type for both
the sending and receiving of RFC
2833 packets.
ONTs will explicitly include the SDP
direction attribute of sendrcv when
the current call connection is in a
2-way conversation.

packetization_in
terval
This parameter controls the
packetization rate which each line of
the voice client (ONT or MDU) will
use in the offer/answer SDP
messages for the RTP packet rate it
requests to receive. The units are
milliseconds between successive
frames. The voice client can offer a
subset of the range of values of 10 to
30 (10, 20, 30 are supported). The
value actually used will be rounded
to the nearest supported value. The
default value is 10 when using FTP
download and 20 when using iConfig
to configure SIP.
