Abstract:
1. A method for regulating a call placement rate of an autodialer comprising multiple communication lines, said method comprising: (a) measuring at least one time delay, each time delay being between a first event and a second event, wherein the at least one time delay includes a first time delay for which the first event is marked by an off hook signal being sent by the autodialer and the second event is marked by a return of dial tone to the autodialer; (b) adjusting the call placement rate of the autodialer in response to the at least one measured time delay; and (c) adjusting a guard time used by the autodialer in response to at least one measured time delay, said guard time being the time between when the autodialer sends an on hook signal associated with an end of a first call and when the autodialer sends an off hook signal associated with an initiation of a second call following the first call on a single communication line; wherein the call placement rate dictates the time between placing phone calls using the multiple communication lines of the autodialer; and wherein the guard time ensures that the single communication line is on hook for an amount of time sufficient to compensate for call congestion at an end office or public switch serving the autodialer.
