VOIP
In order for Echo to collect call audio information, it must be installed on a computer that has an additional network card connected to a mirrored port on a local managed network switch.
The primary network card would have its IP configuration set up so that it is visible on the data LAN. This allows playback of recordings by authorised users, as well as remote control of the Echo server, such as Remote Desktop Connection, if required.
The secondary network card would have its IP configuration set up so that it is visible on the SIP/telephone network. This allows mirrored traffic to be sent to it for the purpose of monitoring and recording by the Echo server.
