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 5 Talk Voice boards can be installed in PCI slots of a single PC chassis enabling port expansion up to 20 ports per system.
Quality voice can be recorded in ADPCM, PCM or WAV formats.
- Network Interface
The Talk Voice 2/4LV+ supports powerful call progress analysis, provides parameters programmable for country-specific regulation ,enhanced DTMF detection & cut-through, plus PABX-specific tone detections.
- Open Architecture
The Talk Voice 2/4LV+ boards share a common driver architecture with other CallURL Talk Voice boards, offering users and developers with the maximum in flexibility and scalability.
All Talk Voice products support standard TAPI and wave drivers for Windows 2000, 2003 and Windows XP (Home or Pro. editions).
