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.
