ESI C-Plus  •  ESI C-Plus Executive

You may have a smaller business, but you still need plenty of big-business capabilities like full-featured voice mail, auto attendant, and conference-calling. And you wouldn’t mind having a built-in help mode, too, so you wouldn’t have to keep looking for the manual. Fortunately for you, there’s the ESI C-Plus. It may be just what your business needs. Be sure to ask also about the ESI C-Plus Executive, which gives you all the great ESI C-Plus features and support for up to two 48-Key Digital Feature Phones.

(For the smallest businesses, IVX C-Class may also be of interest.)

ESI VIP Software


VIP and VIP Professional  •  VIP PC Attendant Console
VIP ACD  •  VIP Softphone

The name VIP means Visually Integrated Phone. It’s a family of software applications that help you manage your ESI voice mail and contacts from your PC. Each VIP application comes in both standalone (SE) and Outlook®-integrated versions. Compared to the basic VIP application, VIP Professional adds still more features, such as auto-recording, text-messaging, and color-coded monitoring of station status.
Be sure also to check out our other VIP Professional-compatible applications: VIP PC Attendant Console, which greatly simplifies managing any busy office’s call traffic; VIP ACD, to maximize your customer service when used with an ACD-equipped ESI system; and VIP Softphone1, which allows you to connect with your ESI Communications Server from a PC via nearly any broadband connection.
