An ESI Communications Server is a powerful tool around which you can build your
organization's entire telecommunications strategy - and you don't have to know it all in
That's because an ESI Communications Server - the ESI-1000, the ESI-600, the ESI-200,
or the ESI-100 - can be a traditional digital business phone system, a fully standards-based
IP telephony system, or any mix of the two. The choice is entirely yours, and the mix can
easily change when your needs do.
