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 ...
Call originator - (or calling party, caller or A-party) a person or device that initiates a telephone call by dialling a telephone number. Call waiting - a system that notifies a caller of another incoming telephone call by sounding a sound in the earpiece. Called party - (or callee or B-party) Caller; Calling party; Conference call (multi ...
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]
Remote call forwarding is also a means for a suburban business to obtain a city-centre local number (with its full large-city coverage area) for inbound calls; while cheaper than a foreign exchange line, this can reduce long-distance telephony costs in markets where local calls are flat-rated but trunk calls are expensive.
The PBX may use this information to route the call directly to a telephone extension within the organization without the need for an operator or attendant. The service provides inbound telephone service for many telephone numbers, often requiring far fewer physical telecommunication circuits to satisfy the demand for concurrent usage than the ...
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.
For example, a dialer could be programmed to use one service provider for international calls and another for cellular calls. This process is known as prefix insertion or least cost routing . A line-powered dialer does not need any external power but instead takes the power it needs from the telephone line.
