  Mediant 800B Gateway & E-SBC 
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.
