A system that incorporates teachings of the subject disclosure may include, for example, capturing images that are associated with a video conference communication session, obtaining a video conference policy associated with the video conference communication session, applying object pattern recognition to the images to detect an object in the images, and retrieve first replacement image content according to the video conference policy. The images can be adjusted by replacing a first portion of the images other than the detected object with the first replacement image content to generate first adjusted video content. The first adjusted video content can be provided to the first recipient communication device via the video conference communication session. Non-adjusted video content can be provided according to the video conference policy to the second recipient communication device via the video conference communication session. Other embodiments are disclosed.

Method and apparatus for providing video conferencing

A method and system are adapted to provide telephony services to aggregate endpoints on an Internet Protocol Multimedia Subsystem (IMS) network. The method includes assigning one or multiple PUIDs for surrogate registration purposes during the provisioning of the aggregate endpoint, performing reliable surrogate registration on behalf of the aggregate endpoint, allowing multiple SBCs to perform surrogate registrations independently for the same aggregate endpoint to achieve reliability, and providing reliable connection from an IMS core to the aggregate endpoints via multiple S/BCs. The system includes one or more Session Border Controllers (S/BC), at least one set of Call/Session Control Functions (CSCF), and an HSS operatively coupled together.

Method and system for implementing aggregate endpoints on IMS networks

Example methods, apparatus and articles of manufacture to provide uniform resource identifier (URI) portability for communication networks are disclosed. A disclosed example method includes receiving a first communication session initiation message identifying a called party, identifying a URI associated with the called party, querying a global URI database based on the URI to identify a domain name associated with a service provider network based on the URI, and sending a second communication session initiation message including the URI to the service provider network via the domain name.

Methods, apparatus and articles of manufacture to provide uniform resource identifier portability

Systems and methods provide virtual CSCFs in an IMS system. The Virtual CSCFs may be virtual S-CSCFs or virtual P-CSCFs. A master virtual CSCF may be used to distribute subscriber data and initial filter criteria to the virtual CSCFs in a group. Thus one of multiple servers may be used for processing call sessions for the same subscriber, thereby avoiding overloading a particular CSCF in an IMS system.

IP multimedia subsystem virtual call/session control functions

A network architecture () provides Voice over Internet Protocol (VoIP) service as well as multimedia and Internet web-based applications while implementing features common in a traditional telecommunications network. In response to an incoming call dialed to an IP endpoint (), the network will process the call, and in particular, convert the call, if in not already in a VoIP format, to such a format, while mapping signaling associated with the call into a compatible format. The VoIP call is then routed to the IP endpoint. In the event that the call requires an associated multimedia or Internet-web-based application, the network will initiate the application. Processing of the incoming call may require accessing of a common database to acquire a location routing number for the call destination. To afford dynamic addressing of the IP endpoints, each may be referenced by a corresponding Universal Resource Locator (URL) (or other indirect mapping) associated with the IP address of the endpoint.
