User's Manual
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.
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.
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.
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.
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.
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.
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.
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.
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.
