The invention discloses a universal hardware abstract port implementing method for voice access equipment. The implementing method for the voice access equipment comprises the steps that an application layer, a protocol layer and a hardware equipment driving layer are provided, and a hardware abstract layer is added between the application layer and the hardware equipment driving layer to shield attention to specific hardware from the application layer; the hardware abstract layer comprises an initialization function block and/or a basic configuration function module and/or an event reporting function module and/or a media operation function module and/or a timing operation function module, the initialization function block, the basic configuration function module and the media operation function module are called by the application layer, the event reporting function module is called by the hardware abstract layer, and the timing operation function module is called by the application layer and the hardware abstract layer. According to the universal hardware abstract port implementing method and calling method, by means of a management layer, the voice access equipment can conveniently have access to different hardware platforms, and development of new hardware and new products is facilitated. The management layer with multiple hardware ports can be achieved at the same time, a developer only needs to maintain one software version, and the maintaining workload is greatly reduced.
