20090245098 | FAILOVER/FAILBACK TRIGGER USING SIP MESSAGES IN A SIP SURVIVABLE CONFIGURATION - Provided are methods, devices, and systems for maintaining a SIP survivable network. The present invention may utilize messages, such as SIP NOTIFY messages, to trigger various network components to failover and failback based on the determined status of the SIP network. | 10-01-2009 |
20090245183 | SIMULTANEOUS ACTIVE REGISTRATION IN A SIP SURVIVABLE NETWORK CONFIGURATION - Provided are methods, devices, and systems for maintaining a SIP survivable network. The present invention is adapted to allow SIP endpoints or User Agents to discover and select the controller or controllers that the SIP endpoint will register with. Selection of the controller or controllers may be based upon the relative attributes of the controllers and the needs of the SIP endpoint. | 10-01-2009 |
20090245492 | SURVIVABLE PHONE BEHAVIOR USING SIP SIGNALING IN A SIP NETWORK CONFIGURATION - Provided are methods, devices, and systems for maintaining a SIP survivable User Agent. The present invention is adapted to allow the User Agent to detect the status of the network, thus providing the User Agent to perform failover/failback operations. The User Agent may be adapted to determine the status of the network based on its own monitoring mechanisms and/or based on messages received from other network components. | 10-01-2009 |
20100054444 | Associating A Topic With A Telecommunications Address - A topic is associated with a temporary communications address such as a temporary telephone number. This assignment may be effected by the user when the temporary address is obtained by the user. Illustratively, a user who simultaneously uses a plurality of temporary addresses associates a different topic with each of those addresses. When a caller calls the temporary address, the call is redirected to the user's real address and the user receives the topic that is associated with that temporary address, and preferably also the called temporary address itself, along with the redirected call, and this information is either displayed or announced to the user. The information provides context for the call to the user, and may optionally be captured in call logs. Illustratively, when the user initiates a call via the temporary address or the topic, the temporary address or the topic is provided to the called party as the caller ID information. The user's identity is thus kept secret. The user may select the calling topic or temporary address from a display of the call logs of past calls that involved the topics and temporary addresses associated with the user's real address. | 03-04-2010 |
20100082839 | SMART LOAD BALANCING FOR CALL CENTER APPLICATIONS - Methods, devices, and systems for smart load balancing are provided. SIP Requests destined for a particular AOR are delivered to one of several registered contact addresses according to associated availability score stored in routing element's contact resolution table. The availability score is periodically updated by the contact entity itself using the SIP PUBLISH mechanism to push the score to the routing element. | 04-01-2010 |
20100082977 | SIP Signaling Without Constant Re-Authentication - A proxy server causes an authentication authority to authenticate a client in response to a first Session Initiation Protocol (SIP) request of the client on a connection. It does not cause the client to be authenticated in response subsequent requests on the connection as long as the underlying connection is not broken, the subsequent requests are on behalf of the same client, the client has not been removed from the system, the client's password has not changed, a “safety net” timer has not expired, or any other policy that the server chooses to enforce. This eliminates the overhead of constant re-authentication in response to each SIP request. | 04-01-2010 |
20100272245 | JOIN-US CALL-LOG AND CALL-ANSWER MESSAGES - The present invention provides methods, devices, and systems for facilitating an ad-hoc conference. More specifically, a “join-us” concept is employed that links functionality in non-real-time messaging systems with real-time ongoing state of calls information in a communications network. This combines the spontaneity and security of an ad-hoc conference call with the join-as-you-can nature of messaging and reservation of conference bridges. | 10-28-2010 |
20110131331 | ALTERNATIVE BANDWIDTH MANAGEMENT ALGORITHM - Methods, systems, and devices are provided that propose allocating bandwidth in a distributed network. According to a decentralized mode of operation, bandwidth between network devices is cooperatively shared and managed, allowing one or more call processing modules to selectively and intelligently place calls or perform activities. A single authoritative mode of operation for a given communication link is also provided, wherein one or more network devices may consult an authoritative member to determine if sufficient bandwidth is available to support an activity. Various triggering events or conditions may facilitate the transition from one mode to another. Audits or accountings are conducted, wherein devices may update or synchronize information stored in a control table related to system bandwidth. | 06-02-2011 |
20140095581 | APPLICATION COMPOSITOR FOR CONVERGED SIP AND HTTP SERVLET APPLICATIONS BACKGROUND - An application compositor enables the creation a sequence of SIP and HTTP servlets that comprises a converged multi-protocol application. Applications are constructed based on rules that declaratively specify a multi-protocol sequence of servlets and the transitions between the servlets, minimizing programmer effort. The application compositor works with a servlet container within an application server to determine the sequence of servlets to be executed by the servlet container when running the application, and is called by the servlet container to perform transitions between servlets. | 04-03-2014 |
