SIP User's Manual
Lower boundary of UDP port used for RTP, RTCP (RTP port + 1)
and T.38 (RTP port + 2). The upper boundary is the Base UDP
Port + 10 * (number of device's channels).
The range of possible UDP ports is 6,000 to 64,000. The default
base UDP port is 6000.
For example: If the Base UDP Port is set to 6000 (default) then:
1) The first channel uses the following ports RTP 6000, RTCP
6001, and T.38 6002, 2) the second channel uses RTP 6010,
RTCP 6011, and T.38 6012, etc.
Note: If RTP Base UDP Port is not a factor of 10, the following
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.
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 330.
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.
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.
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.
