Abstract
Briefly, this invention contemplates the provision of a call pacing method in which the number of calls to dial is periodically (e.g. every two seconds) determined on the basis of anticipated operator availability. The determined number of calls are dialed, subject to a limiting function. Calls in progress are interrupted in a short time slot just prior to first ring if the number of operators available to respond to an answered call falls below a predetermined percentage of the total number of system operators.
Claims14
A method of pacing calls in a call origination management system that has a number of operators to which answered calls are connected, comprising the steps of:
- determining a number of lines to dial;
- dialing calls based on said number of lines to dial established in said determining step;
- establishing an interrupt time slot for a dialed call that extends in duration from a time after a call is dialed to a time prior to a time when said call would be expected to result in a ring signal on a dialed line;
- and
- terminating a call in said interrupt time slot conditionally in order to reduce a ratio of nuisance calls to call attempts.
A method of pacing calls in a call origination management system that has a number of operators to which answered calls are connected, comprising the steps of:
- determining a number of lines to dial as a function of parameters that include a mean time of all calls multiplied by a first constant, and a second constant times a ratio of answered calls to call attempts;
- dialing a number of calls according to said determining step;
- establishing an interrupt time slot for a dialed call that extends in duration from a time substantially after a call is dialed to a time prior to a time when said call would be expected to result in a ring signal on a dialed line;
- determining a ratio of operators available to be connected to an answered call to said number of operators and if said ratio of operators available to said number of operators falls to or below a predetermined ratio;
- a) determining a number of calls to interrupt as a function of a number of available operators, an answer ratio, and a third constant;
- and
- b) terminating calls in said interrupt time slot.
