Make a Choice
ESI offers IVX S-Class with voice mail or Integrated Answering MachineTM. Each system is designed for
easy expansion and upgradability.
IVX S-Class with voice mail
There are two IVX S-Class systems with ESI's award-winning voice mail, including an automated
attendant and a dedicated mailbox for each station. Choose an S-Class system with:
- Four available channels of voice mail and two hours of voice message storage
. . . or . . .
- Six available channels of voice mail and 30 hours of message storage
The automated attendant provides up to 18 branches that conveniently route callers to their
desired extensions or departments, or even destinations outside the system.
Integrated Answering Machine
IVX S-Class with Integrated Answering Machine is tailored for businesses that require only
answering machine capabilities. The system can simultaneously record two messages using any
of the available lines. Messages are accessible from any designated station, and the provided
30 minutes of storage is more than on any conventional answering machine.
Many of the same advanced voice mail features are available — such as live call screening,
off-premises reach-me, external message notification, and a Message Recycle Bin — from a single

Verbal User Guide. You can also train a new employee with the built-in user tutorial.
Intelligent Caller ID
ESI's patented technology displays the caller's name-and-number information with each call, and
stores this information with each voice message. On your ESI Digital Feature Phone, use the
Esi-DexTM speed-dial feature for single-touch storage of caller
information for callback any time.
IVX S-Class with voice mail has patented features that make it simple to share information with your team.
ESI's Quick GroupsTM lets you send a message to other user
mailboxes by pressing the blue VOICEMAIL key followed by the desired station keys —
easily creating a voice mail distribution group on the fly.
IVX S-Class with voice mail allows you to record any call. Simply press the RECORD key on your
ESI Digital Feature Phone and the system will record the call — even conference calls and
Screen calls just as you do with your home answering machine. Listen as callers leave messages
in your mailbox, and intercept a call by lifting the handset.
Message Recycle Bin
The system stores your 10 most recently deleted messages in a Message Recycle Bin.
You can easily recover deleted messages.
A caller forwarded to your mailbox can reach you at an external number — such as your home
or cell phone. IVX S-Class also makes it easy to change your "reach-me" number remotely.
Grows with your business
IVX S-Class easily expands from four lines, eight digital stations and two analog ports to 12 lines,
24 digital stations, and six analog ports. Your ESI phones are also compatible with other ESI IVX
systems. ESI is ready to grow with you.
