ESI Communications Server will serve your needs with fully flexible communications platforms that can support both digital telephones and IP-to-the-desktop in any desired combination. If you have a smaller business, but you still need plenty of big-business capabilities like full-featured voice mail, auto attendant, and conference-calling, ESI has the system. The name VIP means Visually Integrated Phone. It works within Microsoft® Outlook® to help you manage your ESI voice mail and contacts from your PC. VIP Professional adds still more features, such as auto-recording, text-messaging, and color-coded monitoring of station status. ESI products have all of these capabilities and more.
