This specification describes the architecture and protocols that are required for playing announcements in voiceover- IP (VoIP) IPCablecom networks, and is issued to facilitate design and field-testing leading to the manufacture and interoperability of conforming hardware and software by multiple vendors. The will be referred to as the IPCablecom Audio Server Specification. This specification defines a set of signaling protocols that are used to provide announcement services within a cable network. For one of these protocols, this specification defines two new event packages: A Base Audio Package; An Advanced Audio Package
