ESI Hardware and Software Accessories


ESI continues to develop add-on hardware devices and software applications that further enhance the capabilities of their telecommunications platforms. These products provide additional functionality beyond what would typically be expected from a phone system and can often add significant benefits to almost any business.


ESI VIP (Visually Integrated Phone) Software Applications
ESI Presence Management, Access Control and Time Tracking Applications
ESI Bluetooth Voice Integration Devices

ESI VIP Software Appications


Not to be confused with VOIP (Voice Over Internet Protocol), VIP (Visually Integrated Phone) is ESI's suite of software applications designed to provided Computer-Telephony Integration (CTI) capabilities for ESI users. VIP, which integrates with (and requires) Microsoft Outlook, comes in several different versions: VIP Basic, VIP Professional. VIP ACD Agent, VIP ACD Supervisor, VIP PC Attendant and VIP Softphone.


VIP Basic

VIP Basic provides advanced call and message handling capabilities for users of ESI 48-key phones. VIP integrates with Microsoft Outlook, which is required for its use. Key features include:

  • unified messaging - voice mails appear and can be managed through email inbox

  • conversion of voice mails to WAV files - allows voice mails to be transferred or stored electronically

  • point-and-click call handling through a pop-up call control window on the user's PC

  • TAPI integration - call contacts directly from MS Outlook contact list (or other TAPI-compatible software)

  • simplified station programming - point-and-click phone settings and drag-and-drop button programming

  • station call logging - historical list of inbound and outbound calls

VIP Professional
VIP Professional has all of the same capabilities of VIP Basic but takes it one big step further by adding text messaging capability for VIP Professional users. This can provide significant advantages for internal call management in offices or locations with high call volumes.

  • users on the phone can be notified by text message when they have another call or issue to address - elminate the need for distracting 'barge-in' or 'whisper' features

  • Quick Reply buttons allow uses to respond to text messages with pre-set phrases such as "Take Message" or "You Handle"

  • text messaging is only available to VIP Pro users - reduces the likelihood of text messaging being used for non-business purposes

VIP ACD Agent
VIP ACD Agent is designed to further enhance the ESI Communication Servers' ACD (call queuing) feature. VIP ACD Agent users get all the benefits of VIP Professional (see above) plus the ability to view the login and activity status of other agents assigned to their particular ACD group. This combination of real time agent status display, point-and-click call handling, and text messaging between agents allows for effective and efficient call handling.


VIP ACD Supervisor
VIP ACD Supervisor is intended for use by a manager, supervisor owner to monitor in real time the status of one or more ACD (call queue) groups. This software includes all of the benefits of VIP Professional plus:


  • real time display of ACD agent status (logged in, oncall, idle, etc.)

  • real time ACD queue status and statistics (number of calls in queue, wait time, etc.)

  • database capture and historical reporting of summary and detailed call statistics

VIP PC Attendant
VIP PC Attendant is designed for phone attendants or receptionists who are tasked with handling an organization's inbound calls. It turns the attendant's PC into a tool for answering inbound calls, for transferring calls to other stations or mailboxes, and for monitoring the status of calls placed on hold. Features include:


  • all VIP Professional features

  • real time view of all incoming calls

  • real time view of all calls currently on hold, including Caller ID information

  • drag-and-drop transfer and retrieval of calls

VIP Softphone
TheVIP Softphone is a PC-based virtual phone that provides the functionality of a desktop ESI IP Feature Phone. It is particularly useful for road warriors who can benefit from office phone connectivity from remote locations, such as hotel rooms and wireless hotspots. The VIP Softphone includes:


  • all VIP Professional features

  • local (LAN) or remote (Internet) connectivity

  • zero footprint - runs on Windows XP or Vista-based PC or laptop

ESI Bluetooth Voice Integration


With the increasing popularity of Bluetooth cellular devices, ESI has worked to develop two products that will combine the mobility of Bluetooth technology with the power of the ESI Communications Servers.


ESI Cellular Management
Taking business calls on your cell phone while in the office just got easier. ESI's compact Access Device directs incoming cellular calls to your ESI phone. These cell calls are handled just like any other call coming in on your ESI Communications Server land lines, allowing you to take advantage of the features of your office phone system. Here are a few ways this can help:


  • place and receive your cell calls on an ESI 48-key phone

  • route unanswered calls to ESI's voice mail system or leave them on the cellular carrier's voice mail - the choice is yours

  • route incomng cellular calls to a department or group mailbox

  • access your cell phone's voice dialing feature directly from your desk phone

  • share access to your cell phone minutes with others in your office

  • transfer cell calls from your desk phone to your cellular phone so you can continue a conversation even as you leave the office

ESI Bluetooth Headset Interface
This technology provides the capability to 'pair' a Bluetooth headset with your ESI 48-key phone, allowing you to answer and terminate calls directly from your headset. This eliminates the need for costly add-on devices (such as handset-lifters) that are required to provide the same functionality with traditional headsets.
