6. Configuration Parameters Reference
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).
Note: For this parameter to take effect, a device reset is
required.
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).
Notes:
For this parameter to take effect, a device reset is
required.
All devices that participate in the same RTP multiplexing
session must use this same port.
Enables or disables the transmission of RTP or T.38 No-Op
packets.
[0] = Disable (default)
[1] = Enable
This mechanism ensures that the NAT binding remains
open during RTP or T.38 silence periods.
Defines the time interval in which RTP or T.38 No-Op
packets are sent in the case of silence (no RTP / T.38
traffic) when No-Op packet transmission is enabled.
The valid range is 20 to 65,000 msec. The default is
10,000.
Note: To enable No-Op packet transmission, use the
NoOpEnable parameter.
Determines the payload type of No-Op packets.
The valid range is 96 to 127 (for the range of Dynamic RTP
Payload Type for all types of non hard-coded RTP Payload
types, refer to RFC 3551). The default value is 120.
Note: When defining this parameter, ensure that it doesn't
cause collision with other payload types.
