Abstract:
Methods and apparatus to provide a network-based caller identification (CID) service in a voice over Internet protocol (VoIP) network are disclosed. An example method comprises receiving a session initiation protocol (SIP) communication session initiation request message comprising an early-media indicator, disabling a ringtone generator, sending a SIP ringing message containing a session descriptor in response to the early-media indicator, receiving a ringtone based on the session descriptor, and presenting the ringtone to alert a user of a requested communication session.
Abstract:
Methods and apparatus to control a flash crowd event in a voice over Internet protocol (VoIP) network are disclosed. An example method comprises receiving at a VoIP border element a VoIP registration response message having a field representing a priority assigned to a VoIP endpoint, receiving a message from the VoIP endpoint at the VoIP border element, detecting whether a network congestion condition exists, and placing the message received from the VoIP endpoint into one of a plurality of queues based on the priority when the congestion condition is detected.
Abstract:
A technique for providing multimedia communication services to a subscriber includes receiving a communication query for the subscriber, the communication query having an associated requested communication mode. The technique also includes servicing the communication query for the subscriber using the requested communication mode when the requested communication mode corresponds to one of one or more selected communication modes.
Abstract:
A system that incorporates teachings of the present disclosure may include, for example, a Domain Name System (DNS) server having a controller to receive new provisioning information for updating a Fully Qualified Domain Name (FQDN), and update the FQDN with the new provisioning information. The new provisioning information can include among other things a start time for rehoming one or more user endpoint devices (UEs) assigned to a current session border Controller (S/BC), a move-from record comprising a descriptor of at least the current S/BC, a move-to record comprising a descriptor of at least a new S/BC to which to rehome the one or more UEs, a transfer window representing a total time for the rehoming the one or more UEs to the new S/BC, and a pacing parameter for rehoming the one or more UEs to the new S/BC during the transfer window. Additional embodiments are disclosed.
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.
Abstract:
A system that incorporates teachings of the present disclosure may include, for example, a communication device having a controller to transmit to a media server a request for distribution of media content to one or more targeted recipients according to a user profile associated with the communication device that is stored in the media server. The format of the media content can be adjusted by the media server based at least in part on the user profile. Other embodiments are disclosed.
Abstract:
A system that incorporates teachings of the present disclosure may include, for example, a proactive scheduler having a controller element to determine a scheduling conflict between a called party and a calling party according to calendar information of the called party and presence information of the called party. 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:
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.
