    • A method and an apparatus for completing a circuit switched service call in an Internet Protocol network are disclosed. For example, the method receives a session request and queries an tElephone NUmbering Mapping server for a called party, and determines if at least one Naming Authority Pointer resource record associated with the called party is received from the ENUM server. The method determines if a Session Initiation Protocol Universal Resource Identifier is returned, if the at least one NAPTR resource record associated with the called party is received, and processing the session request using the SIP URI, if the SIP URI is returned. The method determines if the processing of the session request using the SIP URI resulted in a successful call completion and processes the session request using a telephone URI, if the processing of the session request using the SIP URI resulted in an unsuccessful call completion.
    • 公开了一种在互联网协议网络中完成电路交换服务呼叫的方法和装置。 例如,该方法接收会话请求并查询被叫方的电话诺顿映射服务器,并确定是否从ENUM服务器接收到与被叫方相关联的至少一个命名权限指针资源记录。 如果接收到与被叫方相关联的至少一个NAPTR资源记录,并且如果返回了SIP URI,则该方法确定是否返回会话发起协议通用资源标识符,并且使用SIP URI处理会话请求。 该方法确定使用SIP URI的会话请求的处理是否导致成功的呼叫完成,并且使用电话URI处理会话请求,如果使用SIP URI的会话请求的处理导致不成功的呼叫完成。

    • A system and method is provided for receiving a voice message, selecting from multiple destinations, transmitting the voice message to a destination and subsequently playing back the voice message after it has been received by the destination. The system has a plurality of access devices which may be coupled to each other over a network such as the Internet. These access devices may include computers, workstations, and the like. Access devices may include a voice decoding device for converting a voice message received over a network into a voice signal for playback to a telephone device and may include a voice encoding device for converting a voice signal received into a voice message.
    • 提供了一种系统和方法,用于接收语音消息,从多个目的地进行选择,将语音消息发送到目的地,并且随后在目的地接收到语音消息之后再播放语音消息。 该系统具有可以通过诸如因特网的网络彼此耦合的多个接入设备。 这些访问设备可以包括计算机,工作站等。 接入设备可以包括语音解码设备,用于将通过网络接收的语音消息转换成用于播放到电话设备的语音信号,并且可以包括用于将接收到的语音信号转换为语音消息的语音编码设备。

    • A method and an apparatus for completing a circuit switched service call in an Internet Protocol network are disclosed. For example, the method receives a session request. The method queries an tElephone NUmbering Mapping (ENUM) server for a called party of the session request, and determines if at least one Naming Authority Pointer (NAPTR) resource record associated with the called party is received from the ENUM server. The method determines if a Session Initiation Protocol Universal Resource Identifier (SIP URI) is returned, if the at least one NAPTR resource record associated with the called party is received, and processing the session request using the SIP URI, if the SIP URI is returned. The method determines if the processing of the session request using the SIP URI resulted in a successful call completion and processes the session request using a telephone URI, if the processing of the session request using the SIP URI resulted in an unsuccessful call completion.
