To monitor ISDN or POTS/Analogue telephone lines, it's necessary to install hardware equipment to physically tap in to them. For these types of telephone line, you'll need some hardware: either our USB Magic Boxes or our PCI (or PCI Express) interface cards.
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.
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.
