Description
Controls whether RTCP report
intervals are randomized or whether
each report interval accords exactly
to the parameter defining RTCP
Mean Tx Interval (in milliseconds).
0 = Randomize; 1 = Don't
Randomize
Defines the Dynamic Jitter Buffer
Minimum Delay (in msec).
Defines the Dynamic Jitter Buffer
frame error/delay optimization.
Selects the DSP load number. Each
load has a different coder list, a
different channel capacity and
different features supported.
Enables or disables detection of
DTMF.
0 = detection disabled; 1 = detection
enabled.
Defines the type of DTMF transport.
0 (DTMF Mute) = Erase DTMFs from
voice transport, not relayed to remote
2 (Transparent DTMF) = DTMFs
remain in the voice stream
3 (RFC2833 Relay DTMF) = DTMFs
are muted from the voice stream and
relayed according to RFC 2833
Notes:
For Nortel H.248 GW applications, the
supported value for
DTMFTransportType is '2'
(Transparent DTMF).
- DTMFTransportType set to
'Transparent DTMF' enables the MG
3200 to negotiate for RFC2833
dynamically (via parsing of the SDP
data provided by the Media Gateway
Controller embedded within the H248
messaging). If the two sides *do not*
agree, the unit will leave the DTMF
digits within the bearer path and it will
be passed to the distant RTP device
within the codec that was established
for the bearer path. If the SDP
information *is negotiated*, then the
