How VoIP recording works[edit]

By definition, Voice over IP is audio converted into digital packets and then converted to IP packets. [1] VoIP recording is accomplished either by sniffing the network or by having the packets duplicated and directed to the recorder--Passive Recording or Active Recording, respectively.
Sniffing(passive recording) is done by connecting to the SPAN (Switched Port ANalyzer) port which allows the VoIP recording unit to monitor all network traffic and pick out only the VoIP traffic to record by either Mac_Address or by IP_Address. This is usually done by connecting an Ethernet cable being between the VoIP recording unit and the router, switch, or hub. Via the SPAN port, the recorder will "sniff" for signaling and RTP (Real Time Protocol) packets that have the identifying information contained in the headers of the packets is designated to record. There are two main ways to capture the RTP packets with the SPAN port. You can SPAN the VoIP Gateway port, giving you all the in/out bound traffic and offers one point of contact for recording. This is especially helpful in a campus with phones in multiple locations across the campus. However this method cannot capture internal, peer-to-peer (phone to phone) calls because their VoIP traffic is sent directly between the phones and doesn't flow through the gateway port. The other method is to set up a VLAN (Virtual LAN) and include all the phones within the VLAN. Then SPAN that VLAN. This will allow recording all in/out bound traffic and internal traffic. The disadvantage is that not all phones at times are on a VLAN or the same VLAN, so multiple SPANS are needed. Another method is to use a concept called RSPAN (remote SPAN), in which the VLAN's that are set to SPAN are trunked across switches to a receiving switch.
