Our Echo PCI Voice Packetizers provide powerful features for building advanced Digital Voice Recorders. Each unit combines a compact form factor with very low power consumption resulting in unmatched reliability.
It uses embedded DSP arrays for D-channel decoding, voice processing and IP packet streaming.
D-channel signalling supports Call Setup, Connect, Clear, DDI number and CLI number decoding. It also supports all major ISDN variants, Q.SIG, DASS-2, DPNSS and various PBX Digital handset D-channel protocols.
Highly secure encrypted IP streaming of the mixed upstream and downstream sides of a conversation.
The speech encoding/compression is 64kbit/s A-law (G.711), 36kbit/s proprietary encoding. The estimated MTBF is 600,000 hours.
