ABSTRACT:
A mass polling system is situated in a central office of a telephone system, and does not employ toll machines or trunk lines leading to toll machines. The mass polling system ensures that a charge record is generated before the beginning of a recorded announcement, during the period while the caller is receiving an audible ring signal. Preferably, the charge record is generated at the initiation of the audible ring signal. In this way billing errors due to early caller disconnect are reduced or eliminated. The mass polling system is responsive to a billing disable command which prevents the mass polling system from causing charge records to be generated when the mass polling system is out of service.
