    • A method and system are disclosed which allow a telecommunications network carrier to apply services and/or features to calls carried by another independent telecommunications network carrier. The method and system enable the receipt of a call, made by a caller to a virtual telephone number, at an MFA switch in a telecommunications network. A determination is made as to whether the call is a special call by way of a Dialed Number Trigger Table. If the call is not a special call it is routed to its destination. Otherwise, a database query identifies from the dialed virtual telephone numbers an actual telephone number representing an end user device corresponding to the virtual telephone number. A determination of whether a service is to be applied to the call is made and, if so, the service is applied. The call is then routed from the MFA switch to a device located outside the telecommunications network for connection to the end user telephone device represented by the actual telephone number.
    • 公开了一种方法和系统,其允许电信网络运营商将服务和/或特征应用于由另一独立电信网络运营商承载的呼叫。 该方法和系统使得能够在电信网络中的MFA交换机处接收由呼叫者对虚拟电话号码进行的呼叫。 通过拨号号码触发表确定呼叫是否是特殊呼叫。 如果呼叫不是特殊呼叫,则将其路由到其目的地。 否则,数据库查询从拨打的虚拟电话号码识别表示对应于虚拟电话号码的最终用户设备的实际电话号码。 确定是否对呼叫应用服务,如果是,则应用该服务。 然后,呼叫从MFA交换机路由到位于电信网络外部的设备,以连接到由实际电话号码表示的终端用户电话设备。
