RTP Port (SIP)
: the default port for RTP/SIP audio streams is 5004 (UDP), but you can enter a
custom value here if desired.
RTP Port (Direct)
: port allocated to the transmission in Direct RTP mode;
should not be the
same as the RTP port for SIP
.
RTP DSCP
: if the transmission network supports DiffServ to manage the media priority, you
can set here the type of service which is assigned to the stream transmitted by the codec.
You should enter here a decimal value, e.g. 46 for the maximal priority code "Expedite
Forwarding". The default value is 0, "Best Effort"
.
Packet Replication
: (see also 2.1.1 and page 10 regarding this feature) you can select here
the setting for packet replication:
0
=> standard mode without replication (default setting)
1
=> packet replication without interleaving
2
=> packet replication with interleaving: the second packet is delayed; robustness is improved
but latency is increased.
Direct RTP Accept
: when this box is checked, the codec accepts incoming RTP streams. If it is
not checked, incoming streams on the Direct RTP port are ignored.
Direct RTP Send only
: if this is activated and the operator sets an outgoing call, the unit does
not expect to receive an RTP stream and rather decodes its own stream. The device keeps
sending data until the user releases the link on purpose. In this use case the "RTP Timeout"
parameter (see further) is irrelevant.
This parameter should not be checked at the same time as "
Direct RTP Accept
".
Direct RTP Timeout
(default 30 seconds): after a link is established, if no data is received
within this time period, the device "releases" the link (i.e. stops sending its own RTP stream)
and comes back to the idle state (
Direct RTP Accept
is unchanged).
Multicast Mode
: if the selected mode is Multicast, the transmission is unidirectional. Select
with this menu if the codec must be
sender
of a multicast stream, or rather
receiver
of such
stream.
Multicast Control Port
: this port number (UDP) is used for sending control packets
accompanying the multicast stream. Default value is 6000.
Multicast Audio Port
: this port number (UDP) is used for transporting the multicast audio
stream. Default value is 6001.
Note: this setting is not related to the RTP Port
settings
valid for RTP/SIP or Direct RTP.
Multicast TTL
: TTL value applicable to the RTP multicast audio stream. Default: 254.
