Outbound switch pacing
First Claim
1. In an outbound, predictive dialing call management system, a method for transferring a number of calls to dial determined by a call manager to an outbound telephone switch, wherein said outbound telephone switch has a rated call switching capacity of x number of calls per y unit of time where y is one hour or less, including the steps of:
- establishing a call budget of a number of calls to dial per unit time by dividing the y unit of time into a plurality of discrete time increments and dividing the x number of calls among said plurality of discrete time increments;
transferring said number of calls to dial determined by said call manager to a budget queue;
transferring calls to dial in said budget queue to said outbound telephone switch at a rate that does not exceed the call budget for each of said plurality of discrete time increments.

Abstract
In an outbound call management system, calls to dial are placed in a buffer queue before transfer to the outbound switch. The rated switch capacity (i.e., X calls per minute) is divided into small submultiples (i.e., Y calls per second) such that short term switch capacity will not be exceeded. Calls are transferred from the queue at the submultiple rate or less depending upon the number of calls in the queue. The time scale is small enough that this instantaneous rate at which calls can be transferred from the queue to the switch does not exceed the instantaneous capacity of the switch. If calls are being placed into the queue at a faster rate than they are sent to the switch, the number of calls in the queue will increase. The call management system will see a resultant apparent increase in the number of placed but unanswered calls. The call management system uses the number of available trunks as a factor when calculating the number of calls to dial, if the number of calls in the queue exceeds a certain number, the call management system will interpret the situation as one in which all the trunks are in use. In this situation, the call management system reduces the number of calls to be dialed.
