Auto diallers are responsible for providing management information to call centre operators, including how many outbound calls each agent has handled. [3] In more sophisticated computer telephony systems, a single system handles both ACD of inbound calls and dialling of outbound calls, allowing agents to be switched between the two as traffic ...

The term "call center" was first published and recognised by the Oxford English Dictionary in 1983. The 1980s saw the development of toll-free telephone numbers to increase the efficiency of agents and overall call volume. Call centers increased with the deregulation of long-distance calling and growth in information-dependent industries. [11]
A dialer automatically inserts and modifies the numbers depending on the time of day, country or area code dialed, allowing the user to subscribe to the service providers who offer the best rates. For example, a dialer could be programmed to use one service provider for international calls and another for cellular calls.
Screen pop is a call centre term that refers to the feature of a computer telephony integration (CTI) which automatically displays customer information via a window or dialog box on an agent's computer upon answering a customer's call.

For example, a company may have a different toll-free telephone number for each product line it sells, or for multilingual customer support. If a call center is handling calls for multiple product lines, the corporate telephone system that receives the call analyzes the DNIS signaling and may play an appropriate recorded greeting.
The call is then transmitted from one end to another via telephone exchanges. The call is switched using a call set up protocol (usually ISUP) between the telephone exchanges under an overall routing strategy. The call is carried over the PSTN using a 64 kbit/s channel, originally designed by Bell Labs.
Calls to such numbers are forwarded to the customer's PBX via the trunks. As calls are presented to the PBX, the dialed telephone number is signaled to the PBX with Dialed Number Identification Service (DNIS) using a prearranged, usually partial format, e.g., the last four digits.
