MediaPack Series
Parameter Description
message is generated: 'invalid local RTP port'.
For detailed information on the default RTP/RTCP/T.38 port
allocation, refer to the Product Reference Manual.
Remote RTP Base UDP Port
[RemoteBaseUDPPort]
Determines the lower boundary of UDP ports used for RTP, RTCP
and T.38 by a remote device. If this parameter is set to a non-zero
value, ThroughPacket™ (RTP multiplexing) is enabled. The device
uses this parameter (and BaseUDPPort) to identify and distribute
the payloads from the received multiplexed IP packet to the
relevant channels.
The valid range is the range of possible UDP ports: 6,000 to
64,000.
The default value is 0 (i.e., RTP multiplexing is disabled).
For detailed information on RTP multiplexing, refer to RTP
Multiplexing (ThroughPacket) on page 333.
Notes:
The value of this parameter on the local device must equal the
value of BaseUDPPort on the remote device.
To enable RTP multiplexing, the parameters
L1L1ComplexTxUDPPort and L1L1ComplexRxUDPPort must
be set to a non-zero value.
When VLANs are implemented, RTP multiplexing is not
supported.
RTP Multiplexing Local UDP
Port
[L1L1ComplexTxUDPPort]
Determines the local UDP port used for outgoing multiplexed RTP
packets (applies to RTP multiplexing).
The valid range is the range of possible UDP ports: 6,000 to
64,000.
The default value is 0 (i.e., RTP multiplexing is disabled).
This parameter cannot be changed on-the-fly and requires a device
reset.
RTP Multiplexing Remote UDP
Port
[L1L1ComplexRxUDPPort]
Determines the remote UDP port to where the multiplexed RTP
packets are sent, and the local UDP port used for incoming
multiplexed RTP packets (applies to RTP multiplexing).
The valid range is the range of possible UDP ports: 6,000 to
64,000.
The default value is 0 (i.e., RTP multiplexing is disabled).
This parameter cannot be changed on-the-fly and requires a device
reset.
Note: All devices that participate in the same RTP multiplexing
session must use this same port.
3.4.2.4 Configuring the General Media Settings
The 'General Media Settings' page allows you to configure various media parameters.
¾ To configure general media parameters, take these 4 steps:
1. Open the 'General Media Settings' page (Configuration tab > Media Settings menu >
General Media Settings page item).
