    • A system that incorporates teachings of the subject disclosure may include an access segment of a mobility network in which routers receive network traffic data from base transceiver stations, forward the network traffic data by way of aggregation routers, originate probe packets directed to a targeted one of the base transceiver station and the aggregation router to determine, by way of an expected reply to each probe packet, reachability of the targeted one of the base transceiver station or the aggregation router. A change from reachability to unreachability of the targeted one of the base transceiver station or the aggregation router is determined to be an indication of service impacted outage. Determined service impacted outages are logged. Reliability metrics, such as average uptime, are computed from reachability status to quantify the impact of service level outages perceptible by the mobile communication devices. Other embodiments are disclosed.

    • A system that incorporates teachings of the present disclosure may include, for example, receiving a session initiation protocol (SIP) subscribe message over a primary call leg requesting outdial event notification on a secondary call leg. Receiving of the call is responsive to a unified messaging system placing a call outside of its local access and transport area. A call is placed on the secondary call leg responsive to receiving outdial information on the primary call leg. Alternative outdial information directed to the calling party is received responsive to the call on the secondary leg being unanswered. Another call is placed on the secondary leg responsive to receiving the alternative outdial information without requiring receipt of another SIP subscribe message over the primary call leg. A calling card server performs SIP messaging associated with one of the SIP notify message or the SIP subscribe message. Other embodiments are disclosed.
    • 结合本公开的教导的系统可以包括例如通过在辅助呼叫支路上请求外部事件通知的主要呼叫支付来接收会话发起协议(SIP)订阅消息。 接收呼叫响应统一的消息系统,在其本地接入和传输区域之外发出呼叫。 响应于在主要呼叫支路上接收到的过时信息,呼叫被放置在辅助呼叫支路上。 响应于辅助线路上的呼叫被接收而被接收到主叫方的替代的外部信息被接收。 响应于接收到替代的外部信息,另一个呼叫被放置在辅助线路上,而不需要在主呼叫支路上接收另一个SIP订阅消息。 呼叫卡服务器执行与SIP通知消息或SIP订阅消息之一相关联的SIP消息。 公开了其他实施例。
