摘要：
本发明提供一种使用黑白名单进行呼叫限制的软交换系统及方法，其中，该系统包括业务处理模块，用于根据当前呼叫消息中的被叫号码与预先存储的黑名单中目的码的地址属性的匹配结果、以及所述当前被叫号码与预先存储的黑白名单中目的码的匹配结果分析是否过滤呼叫；或者根据当前呼叫消息中的入中继携带信息与预先存储的中继黑名单的地址属性的匹配结果、以及所述当前入中继携带信息与预先存储的中继黑名单的匹配结果分析是否过滤呼叫。本发明能够减少使用黑白名单对被叫进行呼叫限制的误操作。
摘要（英）：

The invention provides a soft-switch system and a method by using a black and white list to realize call restriction. The system contains a service processing module used to determine whether to filter calls according to the matching result between a dialed number in the present call information and the target number's address nature in a pre-saved black list and according to the matching result analysis between the dialed number and the target number in the pre-saved black and white list; or to determine whether to filter calls according to the matching result between inwards relay-carrying information in the call information and address nature in the pre-saved relay black list and according to the matching result between the present inwards relay-carrying information and the pre-saved relay black list. The invention can reduce misoperation when using the black and white list to restrict calling the dialed number.
