This invention relates to a method and apparatus for accessing a service bureau or utility via a telemetry call from automated customer premises equipment, such as device state reporting or alarm equipment, without permitting features assigned to the associated customer to interfere with that call. Customer features such as call waiting are canceled for the duration of the telemetry call and arereactivated after the call has been terminated. Advantageously, access from the customer premises equipment to a service bureau or utility may be provided over a telephone line without limiting the customer's choice of telephone features.
