VoIP Plus+ has a lot of features that can be selected, but, in the default state it is meant to
simply collect the Ethernet Packet data and determine if there is a probability of VoIP, or not.
Most of the time, the user will simply select
Start Receiving , and view the Network Streams at
the top and the Frequency graph at the bottom of the screen. When Start Receiving is pressed,
VoIP Plus+ starts processing packets it sees on the Ethernet.
The above figure shows a typical VoIP signature when the TALAN is connected between a VoIP
Phone and it’s router using the VoIP Test Adapter. The type of data to show in the list is set to
NetworkStreams . This is the default.
The list of packets collected can be viewed by selecting the
PacketList above NetworkStreams .
However, due to processing overhead, it is advised to try to do all of the analysis using
NetworkStreams unless the intent is to isolate a specific packet in time. The number of packets
stored for view in the PacketList is also very limited, and old packets are thrown out over time.
The type of graph shown at the bottom of the screen is set to the default
Frequency graph. The
data shown can be set to “Average” or “Peak” or “Current”. Average is the default. Peak is very
useful in finding something when left running over night. Current is helpful in showing exactly
what is happening right now.
