Voice Messaging
Voice messaging systems provide call coverage and messaging services for employees to remotely access their messages out of the office. Other features include call screening, message forwarding, broadcasting messages to more than one recipient at the same time, and paging. Some systems will place a phone call to a preprogrammed number and play a recording when a new message arrives in a user's mailbox.

Fax On Demand
Callers dial in and listen to a menu telling them the various documents they can receive by fax. When they make a selection by speaking or by pressing a touch tone digit, they are prompted to enter the telephone number of their fax machine. The selected fax is transmitted automatically. Companies' can use fax-on demand systems to disseminate information about their products.

F ax Server
A fax server is a computer containing one or more fax boards that is connected to a LAN. A user on the LAN can send computer files directly to the fax server for immediate or delayed transmission. A fax server can also be used to receive incoming faxes over phone lines and store them as computer files for later retrieval. The intended recipient can be notified by a phone call or by a message waiting light on their telephone.

Follow Me Service
Follow-me services enable callers to track down users who are away from their desks by consulting a database of their other possible phone numbers. Follow-me systems may dial out to all possible sites in a programmed sequence. They also allow callers to choose to leave voice mail instead.

Unified Messaging
Many businesses have email, voice messaging, and fax, but these capabilities are offered by separate systems. Employees must check their computers for email messages, their telephones for voice messages, and the fax machine or mail room for fax messages. A unified messaging system can link these local services together, providing a common graphical user interface (GUI). Unified messaging also provides remote services for users by allowing messages in one medium to be forwarded or answered.

Telemarketing/Call Centers
Call Centers are places where many calls are answered and/or made. Typically, an Automatic Caller Distributor (ACD) routes incoming calls to agents who are equipped with a computer terminal for retrieving customer information and for order entry. "Outbound" call centers employ agents to place sales calls, generally using a predictive dialer for automatic dialing.

Order Entry/Order Status
A Computer Telephony system automates the process of ordering a product or checking the status of an order that has already been placed. Users are prompted to enter part or item numbers. Each order is assigned a number that is entered when a status report is needed.
