The ESI-1000 architecture allows expansion when required. Each system cabinet (one
Base Cabinet and up to five Expansion Cabinets) mounts in a standard equipment rack
or on the wall.
The science behind the ESI-600 system is sophisticated, yet simple: ESI has designed
a platform which can support both digital functionality and IP-to-the-desktop, in
any desired combination. It's an amazingly capable all-in-one telephone system.
The innovative ESI-600 design means all vital business communications features you
need are built-in — not added-on.
The ESI-200 architecture allows expansion when required. Each system cabinet (one
Base Cabinet and an optional Expansion Cabinet) mounts in a standard equipment rack
or on the wall.
The ESI-100 architecture allows expansion when required. The Base Cabinet and optional
"piggybacking" Expansion Cabinet are wall mountable and require very little space
in your phone closet.
The ESI-50L and ESI-50 Communications Servers are designed for businesses and enterprises
that require the advanced features of an ESI Communications Server at a smaller
company or location.
While both systems offer a wide array of features and applications, like ESI Presence
Management, the key difference between the two systems is that the ESI-50 includes
built-in support for IP phones, multi-site networking, automated call distribution
(ACD), and multi-tenant applications. The ESI-50L, targeted at a small business
with basic communications needs, can be upgraded to an ESI-50, allowing a small
business to grow its system as its needs expand, while preserving its investment.
