将以独立于底层系统实现的方式为语音消息系统的用户提供一致的交互模式。该界面基于附件a中定义的一套设计指南。该界面支持用户系统模型中描述的所有用户访问语音消息系统功能的能力。在呼叫应答应用程序中，该接口允许呼叫者从所有类型的电话留言。在语音邮件应用程序中，该接口允许用户发送和接收语音消息，并管理存储的数据。

Will provide users of voice messaging systems with a consistent mode of interaction in a way that is independent of the underlying system implementations. The interface is based on a set of design guidelines defined in annex A. The interface supports the ability of all users described in the user-system model to access the features of voice messaging systems. In the call answering application, the interface allows callers to leave messages from all types of telephones. In the voice mail application, the interface allows subscribers to send and receive voice messages and to manage stored data.
