User's Manual 54. Configuration Parameters Reference
Version 6.8 725 Mediant 500 E-SBC
Parameter Description
receives at least a minimum number of consecutive packets
(configured by New<media type>StreamPackets) from a
different source(s) and the device has not received packets
from the current stream for a user-defined period
(TimeoutToRelatch<media type>Msec), it latches onto the next
packet received from any other stream. If other packets of a
different media type are received from the new stream, based
on IP address and SSRC for RTCP/RTP and based on IP
address only for T.38, the packet is accepted immediately.
Note: If a packet from the original (first latched onto) IP
address:port is received at any time, the device latches onto
this stream.

[2] Dynamic-Strict = Device latches onto the first stream. If it
receives at least a minimum number of consecutive packets
(configured by New<media type>StreamPackets) all from the
same source which is different to the first stream and the device
has not received packets from the current stream for a user-
defined period (TimeoutToRelatch<media type>Msec), it
latches onto the next packet received from any other stream. If
other packets of different media type are received from the new
stream based on IP address and SSRC for RTCP and based on
IP address only for T.38, the packet is accepted immediately.
Note: If a packet from the original (first latched onto) IP
address:port is received at any time, the device latches onto
this stream.

[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.
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 (msec)
[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.
