Version 7.2 1041 Mediant 500L Gateway & E-SBC
User's Manual 69. Configuration Parameters Reference
Parameter Description
[3] Strict-On-First = Typically used for NAT, where the correct IP
address:port is initially unknown. The device latches onto the
stream received in the first packet. The device does not change
this stream unless a packet is later received from the original
source.
Note: If you configure the parameter to [0] Strict, the device cannot
perform NAT traversal. In this setup, configure the NATMode
parameter to [1] Disable NAT.
New RTP Stream Packets
[NewRtpStreamPackets]
Defines the minimum number of continuous RTP packets received
by the device's channel to allow latching onto the new incoming
stream.
The valid range is 0 to 20. The default is 3. If set to 0, the device is
left exposed to attacks against multiple packet streams.
New RTCP Stream Packets
[NewRtcpStreamPackets]
Defines the minimum number of continuous RTCP packets
received by the device's channel to allow latching onto the new
incoming stream.
The valid range is 0 to 20. The default is 3. If set to 0, the device is
left exposed to attacks against multiple packet streams.
New SRTP Stream Packets
[NewSRTPStreamPackets]
Defines the minimum number of continuous SRTP packets
received by the device's channel to allow latching onto the new
incoming stream.
The valid range is 0 to 20. The default is 3. If set to 0, the device is
left exposed to attacks against multiple packet streams.
New SRTCP Stream Packets
[NewSRTCPStreamPackets]
Defines the minimum number of continuous SRTCP packets
received by the device's channel to allow latching onto the new
incoming stream.
The valid range is 0 to 20. The default is 3. If set to 0, the device is
left exposed to attacks against multiple packet streams.
Timeout To Relatch RTP
[TimeoutToRelatchRTPMsec]
Defines a period (msec) during which if no packets are received
from the current RTP session, the channel can re-latch onto
another stream.
The valid range is any value from 0. The default is 200.
Timeout To Relatch SRTP
[TimeoutToRelatchSRTPMsec]
Defines a period (msec) during which if no packets are received
from the current SRTP session, the channel can re-latch onto
another stream.
The valid range is any value from 0. The default is 200.
Timeout To Relatch Silence
[TimeoutToRelatchSilenceMsec]
Defines a period (msec) during which if no packets are received
from the current RTP/SRTP session and the channel is in silence
mode, the channel can re-latch onto another stream.
The valid range is any value from 0. The default is 200.
Timeout To Relatch RTCP
[TimeoutToRelatchRTCPMsec]
Defines a period (msec) during which if no packets are received
from the current RTCP session, the channel can re-latch onto
another RTCP stream.
The valid range is any value from 0. The default is 10,000.
Fax Relay Rx/Tx Timeout
[FaxRelayTimeoutSec]
Defines a period (sec) during which if no T.38 packets are received
or sent from the current T.38 fax relay session, the channel can re-
latch onto another stream.
