ESI 600

With the ESI-600, convergence is not just a buzzword; it's a powerful concept around which you can build your organizations entire telecommunications strategy - and you don't have to know it all in advance.

That's because the ESI-600 System for Converged Communications can be: a traditional digital 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.

Like other higher-end ESI systems, the ESI-600 provides built-in voice mail, an automated attendant, and automatic call distribution (ACD). It also supports ESI's VIP and VIP Professional unified messaging solutions, the productivity-boosting ESI PC Attendant Console, and ESI Presence Management.
