Estech Technologies
Estech Systems, Inc. (ESI) designs and markets digital and IP business communications systems. Progressive vision, leading-edge technology, legendary reliability, and outstanding products define ESI. Since its inception in 1987, ESI – a privately held corporation based in Plano, Texas - has enjoyed growth and uninterrupted profitability.
ESI was the first company to build a truly combined telephone and voice mail system, as well as the first to build a purely IP-based business communications system, and has numerous patents granted or pending on its products’ unique designs and capabilities. ESI is highly regarded for supporting unique, real-world applications with practical and effective features.
How does ESI accomplish these feats? By using digital signal processors (DSP’s) – highly powered semiconductors that manage analog functions in a digital environment – and ESI’s innovative system software to replace hundreds of hardware components. This enhances product reliability. It also makes the design and production of new systems, as well as the upgrading of existing systems, more efficient and cost-effective.
