Abstract

Overflow calls intended for a telephone answering center are automatically diverted to an overflow center which automatically answers the overflow calls and records information acquired from the overflow calls. This recorded information is digitally encoded and then transmitted back from the overflow station to the telephone answering center, where it is received and used to allow operators at the telephone answering center to place callbacks, or to take other appropriate action.
