Alternative operator services (AOS) definition
Alternative operator services (AOS) means any intrastate operator-assisted services, other than inmate operator services (IOS), in which the customer and the end user are totally separate entities. The AOS provider contracts with the customer to provide the AOS; however, the AOS provider does not directly contract with the billed party to provide the services even though it is the billed party who actually pays for the processing of the operator-assisted calls. AOS does not include coin-sent calls.
