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.

It also supports ESI's VIP and VIP Professional unified messaging solutions, the productivity-boosting ESI PC Attendant Console, and ESI Presence Management.
