Abstract
A system and method are provided for using electronic serial numbers (ESNS) to determine whether to perform vocoder bypass. In an exemplary embodiment, a terminal device may share a common mobile identification number (MIN) with other terminal devices. The terminal device may answer a page and provide its ESN to an intermediate entity. The intermediate entity may query a database to determine whether the answering terminal device is a mobile station. The intermediate entity may perform vocoding if the answering terminal device is a non-mobile station, or vocoder bypass if the answering terminal device is a mobile station.
