The image below illustrates the usual configuration of network, which enables call recording. How Port Mirroring function is used for VoIP call recording? Computer D can be used for network logging or call recording if we have IP phones instead of computers A and B .Ĭonclusion: Port mirroing allows a particular computer to see the network traffic, which is normally hidden from it.

And administrator has configured the switch to mirror to computer D all network packets, which are transmitted between computers A and B.Ĭomputer D is a listener to the traffic. In Figure 2 you see the similar scenario: the network traffic is sent between computers A and B.īut there is a small difference: this switch supports port mirroring function.

Other computers do not see the traffic, that is not destined for them. Conclusion: With a regular switch the network traffic is visible only to computers, which directly participare in a communication. Other computers (C and D) do not see this network traffic. When the switch receives a packet from A to B, it routers this packet to port #3 (because B is on port #3). Port #1 (first on the left) is not connected.The MAC table in the memory of the switch contains information on which port is connected to particular computer.
