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. A mote detailed explanation is presented below.

NEC NEAX is plugged into port 24 (the Observe port) on the data switch. Port mirroring is enabled on this port.

The CallRex Server is plugged into port 1 on the switch. Every packet going to port 24 is mirrored to port 1, thus enabling CallRex to sniff every packet going to and from the NEC NEAX.
