1. An apparatus for Voice over IP capturing in a network, the apparatus comprising:
- a data receiver, tapping the network, and configured to receive data packets transmitted over a communication link between a first party and a second party coupled to the network;
a VoIP identifier configured to determine if received data packets are Real-time transport protocol (RTP) VoIP data packets based on compliance with a known standard of the RTP and if the VoIP data packets are qualified for forwarding to a recording device based on Computer Telephony Integration (CTI) data; and
a forwarder configured to change a destination IP address and port of a copy of qualified RTP VoIP data packets and to forward the copy of qualified RTP VoIP data packets to the recording device via a first switch port external to the apparatus, and to forward the received data packets back to the network via a second switch port external to the apparatus.

15. A method for Voice over IP capturing in a network, the method comprising:
-
receiving packets transmitted over a communication link between a first party and a second party coupled to the network, by an apparatus tapping the communication link; determining if received data packets are Real-time transport protocol (RTP) VoIP data packets based on compliance with a known standard of the RTP and if the VoIP data packets are qualified for forwarding to a recording device according to Computer Telephony Integration (CTI) data; changing destination IP address and port of a copy of qualified RTP VoIP data packets; forwarding the copy of qualified RTP VoIP data packets to the recording device via a first switch port external to the apparatus; and forwarding said received data packets back to the network via a second switch port external to the apparatus. - View Dependent Claims (16, 17, 18, 19, 20, 21, 22, 23, 24, 25)
