Technical Description

Configuration
The Talk Voice 2/4LV+ provides two/four telephone line interface circuits for direct connection to analog loop start lines. Up to 4 Talk Voice boards can be installed in a single PC chassis enabling port expansion up to 16 ports per system.

Network Interface
The Talk Voice 2/4LV+ supports powerful call progress analysis, provides parameters programmable for country-specific regulation ,enhanced DTMF detection & cut-through, and PABX-specific tones detection. Quality voice recording in ADPCM, PCM or WAV formats.

Open Architecture
The Talk Voice 2/4LV+ boards share a common driver architecture with other Talk Voice boards, offering users and developers both, maximum flexibility and scalability. All Talk Voice products support standard TAPI and wave drivers for Windows 2000 and Windows XP.
