ini File Parameter Description
EnableUDPPortTranslatio
n
 [0] = Disable UDP port translation (default).
 [1] = Enable UDP port translation.
When enabled, the device compares the source UDP port of the first
incoming packet, to the remote UDP port stated in the opening of the
channel. If the two UDP ports don't match, the NAT mechanism is
activated. Consequently, the remote UDP port of the outgoing stream is
replaced by the source UDP port of the first incoming packet.
Note: The NAT mechanism and the IP address translation must be
enabled for this parameter to take effect (DisableNAT = 0,
EnableIpAddrTranslation = 1).
NoOpEnable
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.
NoOpInterval
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.
RTPNoOpPayloadType
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.
EnableDetectRemoteMA
CChange
Changes the RTP packets according to the MAC address of received
RTP packets and according to Gratuitous Address Resolution Protocol
(GARP) messages.
 [0] = nothing is changed.
 [1] = If the device receives RTP packets with a different source MAC
address (than the MAC address of the transmitted RTP packets), then
it sends RTP packets to this MAC address and removes this IP entry
from the device's ARP cache table.
 [2] = The device uses the received GARP packets to change the
MAC address of the transmitted RTP packets.
 [3] = both 1 and 2 options above are used (default).
