Our Echo GSM Voice and SMS Recording devices provide powerful features for building portable to large channel count enterprise level GSM Voice and SMS Recorders. The PCI model occupies a single standard 5V PCI slot and combines a compact low profile form factor with low power consumption for medium density industrial chassis applications.
The 19" rack version with GSM plugin modules is available with 8 or 16 modules for high density applications. The USB model features a USB 2.0 compatible high throughput USB interface and combines a compact form factor with low power consumption for ultimate portability.
On-board DSP and large streaming buffers impose very little demand on system and application resources. Signalling support for Call Setup, Connect, Clear, DDI number, CLI number and SMS message decoding and encoding.
The speech encoding/compression is 64kbit/s A-law (G.711), 36kbit/s proprietary encoding. The estimated MTBF is 400,000 hours.
