ISDN PRI/BRI or Analogue trunks

For these types of telephone line, you'll need some hardware: either our USB Magic Boxes or our PCI (or PCI Express) interface cards.

These passively intercept your phone lines, monitoring and recording all calls that pass along your lines.

USB Devices (Magic Boxes)

Our Echo USB Voice Recording devices provide powerful features for building small to medium channel count portable Digital Voice Recorders. Each model features a USB 2.0 compatible high throughput interface and combines a compact form factor with very low power consumption resulting in unmatched reliability.

D-channel signalling supports Call Setup, Connect, Clear, DDI number and CLI number decoding. Supports all major ISDN variants, Q.SIG, DASS-2, DPNSS and various PBX Digital handset D-channel protocols. Simultaneous recording on all channels of both upstream and downstream sides of a conversation.

PCI devices

The Echo PCI Voice Recording boards provide powerful features for building advanced Digital Voice Recorders. Each card only occupies a single standard 5V PCI slot and combines a compact form factor with very low power consumption resulting in unmatched reliability.

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.
