    Abstract: A process that incorporates teachings of the present disclosure may include, for example, recording, by a mobile communication, media content in a first media format and accessing a wireless media system by way of a wireless communication network. A request is transmitted to the remote media system to store the recorded media content in the first media format. The recorded media content is transmitted to the remote media system, without retaining a copy of the recorded media content in the first media format at the mobile communication device. Other embodiments are disclosed.

    Abstract: A system for communicating with an Internet Protocol Multimedia Subsystem (IMS) network is provided. A system that incorporates teachings of the present disclosure may include, for example, an intermediate node having a controller element to receive from a non IP Multimedia Subsystem (IMS) compliant node a Session Initiation Protocol (SIP) message having a calling party number and a called party number, and insert in the SIP message a request that instructs a receiving IMS-compliant node to bypass validation of the calling party number. Additional embodiments are disclosed.

    Abstract: Methods and apparatus to mitigate a Denial-of-Service (DoS) attack in a voice over Internet protocol (VoIP) network are disclosed. An example method comprises receiving a communication session initiation message from a communication session endpoint, determining whether the communication session endpoint is associated with a probable DoS attack, and sending to the communication session endpoint a communication session initiation response message comprising a DoS header when the communication session endpoint is associated with the probable DoS attack.

    Abstract translation: 公开了在因特网协议语音（VoIP）网络中减轻拒绝服务（DoS）攻击的方法和装置。 一种示例性方法包括从通信会话端点接收通信会话发起消息，确定通信会话端点是否与可能的DoS攻击相关联，以及当通信中发送包括DoS头部的通信会话发起响应消息时，向通信会话端点发送通信会话发起响应消息 会话端点与可能的DoS攻击相关联。

    Abstract: 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.
