System Options
Unified messaging - VIP
VIP (Visually Integrated Phone) is available in an Outlook®-integrated edition and a standalone edition (SE), and comes in two “flavors”: the basic VIP and VIP Professional. Each configuration is licensed independently, with easy migration from VIP to VIP Professional. Each lets you intelligently do the following from your PC’s screen:
- Manage your telephone calls
- Manage your voice mail
- Organize your contacts
- Log all your inbound and outbound calls
- Quickly program your ESI desktop phone
With VIP Professional, you also get:
- Enhanced, more informative user interface
- Secure text-messaging
- Auto-recording capability2
- Compatibility with Outlook-integrated and standalone versions of VIP PC Attendant Console, VIP ACD, and VIP Softphone
And, speaking of those other products . . .
These independently licensed members of the VIP product family, all compatible with VIP Professional, add their own specific capabilities (click their links for more information):
- VIP PC Attendant Console – Makes it easier for even the busiest attendant to handle call traffic efficiently.
- VIP ACD1 – Helps you improve the quality of your customer service when used with ESI systems with built-in ACD (automatic call distribution).
- VIP Softphone1 – Lets you use your PC to connect to your IP Server 900 or ESI Communications Server from nearly any location with a broadband connection.
Regardless of your selected configuration, VIP is easy to implement. It connects to your existing local area network (LAN) and is non-invasive. There’s no need to upgrade the LAN or install Microsoft® Exchange® – thus avoiding a costly and impractical solution for the small to mid-size business.
Media management
Can collect and store:
- Recordings of selected phone calls (call logging)
- Video camera recordings
- Detailed call activity (more commonly known as SMDR data)
- Building access events1 from across your facility
With ESI Media Management, you decide who’s authorized to access the stored information, so there’s no worry that information is getting into the wrong hands.
Media Management provides these and other benefits:
- Recording of all calls to and from employees for improved customer service and quality control
- Capture and review of video from around your facilities using standard video cameras
- Use of live video to improve facility monitoring and enhance access control
- Review of system-wide building access events1 and call detail records for your employees
- Quick location of a collection of related events using simple search criteria.
Mobile Messaging
ESI Mobile Messaging combines the advanced capabilities of your ESI business communications system with the convenience of users’ existing e-mail accounts. When you receive a message (a voice mail or a recording) at your extension or guest mailbox, you also receive an e-mailed notification to which a .WAV of the message is attached. The notification’s header contains information about the message — the Caller ID name and number, as well as the call’s date, time, and duration. ESI Mobile Messaging also lets you quickly do these (and more):
- Listen to a message on your PC or “smartphone” – Play back a message on your PC or “smartphone” by simply double-clicking the attachment
- Share messages – Forward important messages to interested individuals, even if they’re not on your ESI system
- Choose which messages to handle and how to manage them – If you have numerous messages, you can directly access any message right away.
- Remotely manage messages – You can manage messages using Web mail from: a home PC or laptop; a personal (or alternate) e-mail account; or a “smartphone”
- Store important messages – Save a message attachment to a hard drive or USB flash drive
- Choose two e-mail accounts at which to receive e-mailed notifications of messages
Cellular Integration and bluetooth
Simplify your communications using Bluetooth technology. The mobility that Bluetooth® technology provides and the power of your IP Server 900 or ESI Communications Server have been combined to improve your productivity. Two ESI Bluetooth Voice Integration products offer unique capabilities to make you more efficient:
- ESI Cellular Management lets you manage your cell phone calls along with your normal business calls, all from your desktop phone.
- The ESI Bluetooth Headset Interface lets you use any compatible Bluetooth headset with your compatible ESI desktop phone.
Get the best of both worlds. Busy professionals who frequently take business calls on a cell phone while in the office now can enjoy the convenience of taking those calls on a compatible ESI desktop phone. ESI Cellular Management eliminates the awkwardness and loud interruptions caused by cell phone use in the office. Simplify your life with this compact Access Device that directs incoming cell calls to your desktop phone.* Cell calls are handled by the IP Server 900 or ESI Communications Server just like any other call, so you can get all the advantages and standard ESI features of your office phone system – features like call forwarding, call transfer, conferencing, live call recording, and more.
Here are just a few of the ways ESI Cellular Management can simplify your business communications when in the office:
- Make and take your cell phone calls on a compatible ESI desktop phone
- Route unanswered cell calls to ESI’s advanced voice mail, or leave them on the cellular carrier’s voice mail – whichever best suits your needs
- Enjoy improved call coverage by routing cell calls to a department or group mailbox
- Access your cell phone’s voice-dialing feature directly from your desktop phone
- Share access to your cell phone minutes with others in your office and save money by fully utilizing your cellular calling plan.
Bluetooth Headset Interface
Don’t be tied down by wired headsets. The ESI Bluetooth Headset Interface lets you “pair” a standard Bluetooth headset with a compatible ESI desktop phone, so you can seamlessly answer, originate, and terminate phone calls directly from the headset. Using ESI’s integrated interface, you get all the standard headset features available on the IP Server 900 or ESI Communications Server, plus the mobility of Bluetooth. Don’t hassle with expensive add-on devices like headset lifters. Let the ESI Bluetooth Headset Interface give you the freedom to achieve a higher level of productivity.
Cordless Keysets
ESI’s Cordless Handset II provides mobility to users who are constantly on the move in the office. There are three models of the compact, lightweight Cordless Handset II, and each provides the same rich feature set as the 24-Key Feature Phone, plus ESI’s exclusive Quick Switch™ for maximum ease when switching back and forth between your ESI desktop phone and your Cordless Handset II.
For extended range and to elimenate dead spots optional repeaters can be added to the system.
