How
CallRex Works
Overview
CallRex
Records/monitors telephone calls by sniffing packets
traversing across the data network. Packet sniffing is
achieved by enabling port mirroring on the data switch. Port
mirroring is supported by most data switches and when
enabled will send a copy of every packet destined for one
port to another port
