Abstract: This invention relates to a method and apparatus for preparing a billing record for a special service telecommunications call such as a call over a software defined network or a direct service dialing capability call. These calls are characterized by the fact that in order to properly route and bill such calls, remote shared data bases must be consulted to obtain the necessary information, much of which is recorded in the billing record in order to properly charge the customer and to give that customer information about its calls. Special billing information for these special service calls is accumulated in an enhanced billing register capable of storing the special billing information for these special service calls. After timing for two seconds following the receipt of an answer for the call, all the accumulated billing information is transmitted to a separate processor, one of whose functions is the preparation and formatting of billing records.
