A system and method for uniquely identifying an SIP device extends the SIP communications protocol with an end point identifier, carried for example in the header of an SIP transmission. The end point identifier is useful for routing, registration, subscription, and authentication. The end point (device) of a given user epid can be uniquely identified by creating a key from an epid and a user's address-of-record (URI). This in turn enables improved connection management and security association management when the connections/IP addresses are transient, such as when HTTPS tunneling is used.

End-point identifiers in SIP

An interactive information distribution system that facilitates automatic transmission of a variety of information packets to the communication devices of a calling party and parties called during a call. The information packets are comprised of actual files and or links to files or websites, and are automatically transmitted following the initiation of a call. Upon initiating a call, an indicator that may include metadata linked to information packets is processed to identify at least one database for locating information packets to which the metadata is linked. The interactive information distribution system also includes a verbal communication conversion engine that allows verbal telephone communications to be converted to text and filtered to generate keywords which are used in additional database searching to identify additional information packets. The information packets automatically identified are retrieved from a database and are transmitted to the communication devices of parties participating in a call during the call.

The present invention allows a server to delay allocating resources to a client's request. When the client requests a feature that requires server resources, the server accepts and acknowledges the client's request, but the client is prohibited from using the requested feature until further notice from the server. For example, during an authorization process, the server allocates only the minimum resources required to maintain the session and to authorize the client. Thereafter, the server allocates the resources necessary to support the client's request only when the resources become available. Until then, the server maintains the communications session without supporting the request. Thus, the server shepherds its resources rather than committing them at the whim of a client. Also, a client need not repeat its request if the server cannot immediately satisfy it; instead, the server accepts the request and then later begins to support it when adequate resources become available.

A method and system for identifying whether an electronic communication is likely to be unwanted by the recipient is provided. A trust system relies on a trust provider, such as a sending domain, to indicate whether an electronic communication is likely to be unwanted. The sending domain may assign its trust level to the electronic communications based on various factors. Upon receiving the electronic communication and the trust level assigned by the sending domain, the receiving domain may determine whether to forward the electronic communication to the recipient based on the trust level. If a sending domain consistently provides trust levels that are accurate assessments of whether electronic communications are unwanted, then the receiving domain learns to trust the trust levels assigned by the sending domain. In contrast, if the assigned trust levels are not accurate, then the receiving domain learns not to trust the sending domain and may discard all message from the receiving domain without forwarding them to the recipients.

A distributed authentication model that operates within a protocol-based sphere of trust. Rather than being able to communicate with any one of the computing systems internal to the sphere of trust, the amount of authentication is reduced by having the external computing systems initially communicate with a specific edge internal computing system. Many if not all of the internal computing systems then delegate the task of authentication to the edge computing system, and will rely on any authentication performed by the edge computing system. This allows the task of authentication to scale well for large protocol-based spheres of trust.
