The consumer can make multiple calls after a single card insertion by using the Next Call key rather than having to re-insert the card.

Plus, it is designed to accommodate emerging technologies. Downloadable code allows terminals to do an automated firmware upgrade over an X.25 line.

And as consumers take advantage of the M1245 terminal's many conveniences, profitability for the PSP and site agent can increase through follow-on calls, directory assistance and call commissions.

Introducing eMillennium - The evolution of Public Access

Welcome to the next level. QuorTech Solutions has forever changed the face of public communication by bringing the power and attraction of the Internet to the already well established Millennium payphone family.

eMillennium is public communication for the 21st century. It offers superior multi-pay voice access in combination with powerful, yet user-friendly web applications. Users can check e-mail, get stock quotes, make on-line purchases, even cruise the Internet all while talking on the phone. A built-in Ethernet data port provides the additional option of high-speed web access through a laptop computer.

eMillennium is as functional as it is eye catching. The 6.5" full VGA colour screen offers amazing visual clarity, while the standardized keyboard and built-in mouse make for easy and familiar navigation. Whether you're a current Millennium operator or new to the Millennium line of phones, upgrading to eMillennium is simple.

The eMillennium dimensions are the same as any other payphone terminal, so no new furniture is required.

Best of all, eMillennium is designed with customization in mind. It's built on an open platform, so both advanced HTML and Java applications can be developed quickly.

Direct connections with taxis, hotels, restaurants or any other imaginable product or service can be the first thing a user sees when they approach the phone.

eMillennium is connection without limits. It ushers in an era where the boundries of old public access no longer exist. The future of communication is here.

The future is eMillennium.

• TFT 6.5“ VGA LCD Display provides superior advertising and Internet browsing opportunities. Take advertising and cross-sell services to the next level.
• Voice Prompts offer dialing assistance. User-friendly system enhances operational effectiveness.
• Language Selection and Operating Assistance is available through clear on-screen prompts and “Soft Keys”.
• Standardized Keyboard with Mouse Controls allows for easy operation. Anyone familiar with a standard keyboard will feel right at home.
• High Speed Ethernet Port is the evolution of the Millennium data jack. Plug-in and browse from your own laptop at Ethernet speeds. Send e-mail, transfer files – anything is possible without wasting valuable time.
• Built-in Self Diagnostics monitors terminal performance and can notify the nearest service center when attention is required.
• Branded Upper Bezel calls attention to the service provider's name.
• Multi-Card Reader gives customers more options for payment by accepting both magnetic stripe and “smart chip” cards. Card Icons identify which cards are accepted.

The Millennium Inmate System is a mature Inmate Services platform which has been developed by QuorTech to offer Inmate Service Providers with a network compatible, system based solution, which can provide broad service capabilities nation-wide. In addition, the Millennium System investment provides several opportunities to expand Sprint services into other transaction based businesses.

The Millennium Inmate Payphone and support system provides prison officials with additional control features which are needed to compete in this market today. Features offered include limited call duration, programmable curfew periods, and blocking of calls to specified numbers (numbers may be blocked per inmate, per prison or nation-wide).

The system also allows calls to specific 1-800 numbers and provides an emergency / auto dialer button. It can also assist with recording and monitoring efforts of prison officials by interfacing to recording equipment, providing call detail records and advising both calling and called parties that the calls may be monitored or recorded. Prison officials are able to adjust controls and request a variety of reports through software on their PCs.

There are two types of the Millennium Inmate payphones included in the Millennium Inmate Systems solution:

Millennium Inmate Payphone with card-Reader

Millennium Inmate Payphone without Card-Reader

No technical or physical specification has been posted on the website.

Judging by the advertising-text, the hardware corresponds to one of the Coin-Only- or Card-Only-devices and additional software to be run on the prison-computer-system - so probably just an extension of the Millennium Manager.

No detailed specification has been posted on the website.

The Millennium Manager is said to cost around 1 Million US-Dollars if to be bought and there are not many know running instances of it - one is at WiMacTel/Quortech. Price aside, another reason for this might be, that the software only runs on HP Tandem-servers.

Except for the eMillennium and the M1361 Desk Terminal, (probably) all phones can be upgraded with the following options. At any given time, there can only be one option installed.

• No upgrade / blank panel
• 5 Button Quickdial-panel
• 10 Button Quickdial-panel
• SMS/eMail/TTY-keyboard

Each phone can also be fitted with a modem-/data-jack, which is installed on the side of the box. This upgrade does not inhibit the above mentioned addons. The datajack has also been seen as an integrated part of the cardreader-bezel.

Also, it is (probably) possible to pass from one phone-type to another by replacing the card-reader and/or display.
