20100319059 | SIP DIGEST AUTHENTICATION HANDLE CREDENTIAL MANAGEMENT - Methods, devices, and systems for controlling access to a password protected resource are provided. More specifically, different communication profiles can be mapped to a single user and that user can utilize a single password to gain access to the password protected resource using any one of his/her communication profiles. Each communication profile may have a unique authentication value associated therewith, but each unique authentication value may be determined based on the single password, thereby eliminating the need for a user to remember multiple passwords for each of his/her communication profiles. | 12-16-2010 |
20100325249 | PLUGGABLE CONTACT RESOLUTION - Methods, devices, and systems are provided for taking a pluggable extension and applying it to a unique set of a user population to handle their preferred and user-centric alerting relationships. More particularly, the pluggable extension allows a user to have their personalized contact resolution algorithm applied by a server to calls initiated by them or directed toward. The contact resolution algorithm is pluggable to any server and does not need to be built into the server itself. Moreover, multiple users can refer to and use the same pluggable contact resolution algorithm. | 12-23-2010 |
20100329121 | INTERNAL/EXTERNAL NETWORK IDENTIFIER - Methods, devices, and systems are provided for marking one or more entities of a call as internal/external such that certain call features can be invoked by servers and other devices residing behind a gateway. More specifically, entities of a call can be marked as internal/external based employing an assessment algorithm to determine whether the calling endpoint is an internal or external endpoint and/or whether a user of the calling or answering endpoint is an internal or external user. Once this determination is made, the call can be marked accordingly such that the appropriate features can be invoked. | 12-30-2010 |
20110066694 | SIP ENDPOINT ENHANCER - Methods, devices, and systems are provided for enhancing the functionality of a communication device, such as a communication endpoint. This provides the ability to enhance less intelligent SIP endpoints with required features to support a richer user experience.

20110066707 | NETWORK FRAMEWORK ASSOCIATING NON-ENTERPRISE PHONE WITH ENTERPRISE USERS - Methods, devices, and systems are provided for identifying unique points in communication processing for substituting and restoring identities associated with the communication. These specific replacements facilitate communication requests to-and-from external identities to be treated similar to communication requests to-and-from enterprise users, thereby allowing enterprise users to access enterprise-based communication preferences and services via non-enterprise devices. | 03-17-2011 |
20110122863 | ENHANCED CALL PRESERVATION TECHNIQUES FOR SIP-BASED COMMUNICATION NETWORKS - Methods, devices, and systems are provided for preserving connections, especially in a SIP environment. More specifically, the connection preservation techniques presented in this document enhance the RFC 4028-based session refresh approach in order to provide media connection preservation for calls that experience end-to-end signaling loss or refresh failures. Specifically, participants on a call can continue to exchange media despite the loss of control at the SIP signaling plane. | 05-26-2011 |
20110289203 | SIP MONITORING AND CONTROL ANCHOR POINTS - The concept of anchor points is introduced. Anchor points, and specifically Session Initiation Protocol (SIP) anchor points, serve as a media and call control point that is established on a per-user basis which can then be shared by any application. The use of an anchor point allows for applications to become aware of and control a communication late or cease monitoring and controlling a communication session early without disrupting the session or introducing a significant amount of control or media delay. | 11-24-2011 |
20110289219 | SIP ANCHOR POINTS TO POPULATE COMMON COMMUNICATION LOGS - The concept of a centralized communication log is provided. Anchor points, and specifically Session Initiation Protocol (SIP) anchor points, serve as a media and call control point that is established on a per-user basis which can then be leveraged by a communication log service. Such a communication log service is able to determine accurate and real-time communicant information for a communication session and populate a centralized communication log with the same. Such a communication log is, therefore, accurate with respect to multiple users in a system, highly available, and scaled horizontally. | 11-24-2011 |
20120139726 | INTELLIGENT MUSIC ON HOLD - Prior art solutions only implement absolute music-on-hold suppression at the conference bridge. The present disclosure moves the intelligence and control capabilities to the entity implementing music-on-hold functionality and also provides mechanisms for applying the music-on-hold treatment more intelligently. Intelligent and flexible music-on-hold control algorithms are disclosed which make conference participation more convenient and enjoyable. | 06-07-2012 |
20120148037 | THIS CALL - An in-progress call can be manipulated such that user devices in proximity to the in-progress call, but not initially part of the call, are enabled to join the in-progress call. Determining that a user device is in proximity to an in-progress call may include detection, by the user device, of an in-progress call. Alternatively, or in addition, a communication device involved in the in-progress call may detect a user device and query the user device as to whether it has permissions to join the in-progress call and, if so, whether it wants to join the in-progress call. | 06-14-2012 |
20120163571 | HIGHLY SCALABLE AND DISTRIBUTED CALL/MEDIA MODELING AND CONTROL FRAMEWORK - A highly scalable and distributed call/media modeling and control framework is described. In particular, a plurality of anchor point servers are provided which enable one or more applications to exert call and media control over in-progress communication sessions even though the applications were not originally bound to the communication session during its setup. | 06-28-2012 |
20130022192 | EFFICIENT AND COST-EFFECTIVE DISTRIBUTED CALL ADMISSION CONTROL - A distributed call control system is provided that can allot bandwidth amongst several call controllers. The distributed call control system includes one or more access elements that interface with a cloud that execute two or more instances of call processing servers that administer call control. The cloud members negotiate and determine bandwidth allocation amongst the members and the access elements. If an access element requires more bandwidth, the access element assesses its own needs and requests more bandwidth from the cloud. The negotiation and requests for bandwidth are accomplished with a set of dynamic and static bandwidth data that regiment the control of the bandwidth. | 01-24-2013 |
20130173812 | SIP TRANSFER IN A BACK-TO-BACK USER AGENT (B2BUA) ENVIRONMENT - The system generates a change in the SIP INVITE message during a call transfer. Here, a user relation element involved in the call can change the header information in the message to include the endpoint view of the transferring party. Thus, the INVITE message is redirected to the transferring party's user relation element, which can interpret the received message and “unravel” the B2BUAs in the existing call path. The system includes changes in the user relation element to effect the message change and interpret the message once received. Changes to the user relation element forgo the need to change the communication endpoints. | 07-04-2013 |
20130212242 | GLOBAL SESSION IDENTIFIER - Systems and methods are described for creating and managing Global Session Identifiers (GSIDs) for communication sessions. GSIDs provide a way to globally identify communication sessions including those communication sessions that have experienced one or more topology changes. The GSID may be considered a header itself or a value within a header and information contained within a GSID can be used to trace backwards through time to find the session segments that led up to (or exist concurrently to) a currently signaled session. | 08-15-2013 |
20130301822 | PARALLEL FORKING WITH AOR CHAINING - The concept of chained parallel forking is introduced. Addresses of record are included in a contactee's contact resolution preferences to enable an incoming INVITE message to be routed to one or more users as well as other devices, per the contactee's contact resolution preferences. A communication system configured to execute the chained parallel forking contact resolution process is also described. | 11-14-2013 |
20130311825 | CALL RESTORATION IN RESPONSE TO APPLICATION FAILURE - A communication system, method, and components are described. Specifically, the method described herein provides the ability for an application sequence of a communication session to be reconstructed during the communication session and even though SIP standards dictate that the reconstruction of the application sequence should be denied and the session should be terminated. | 11-21-2013 |
20140096198 | SECURE CALL INDICATOR MECHANISM FOR ENTERPRISE NETWORKS - The concept of a secure call indicator is introduced. In general, the secure call indicator is capable of inspecting the security of signaling associated with Session Initiation Protocol (SIP) messages and comparing the security with media descriptions of the actual media path of the SIP messages. Furthermore, the secure call indicator may be configured to indicate the security associated with a communication session via a physical or virtual notification system. | 04-03-2014 |
20140280018 | METHOD, APPARATUS, AND SYSTEM FOR PROVIDING AND USING SUBSCRIPTIONS AND FILTERING BASED ON TREE STRUCTURES - Methods and systems are provided such that users, servers, and applications may utilize an extensible data filtering model where data is organized into a tree with filtering available at any node level. Accordingly, the node filtering and propagation method and system allows for the efficient management and automatic replication of common information for multiple applications at all data levels. | 09-18-2014 |
20140282619 | METHOD, APPARATUS, AND SYSTEM FOR PROVIDING AND USING MULTI-PROTOCOL EVENTING - Methods and systems for providing an elegant and efficient multi-protocol eventing layer are disclosed. The multi-protocol eventing layer includes a converged container capable of handling multiple types of protocols to manage events while using an open source database. Accordingly, the multi-protocol eventing layer efficiently provides real-time or near real-time eventing to a plurality of devices for scalability and performance enhancement. | 09-18-2014 |
20150052208 | INVOCATION OF SEQUENCED APPLICATIONS BASED ON DYNAMIC PARAMETERS - Systems and methods are described for selecting applications for incorporation into an application sequence. The selected applications provide one or more features to a communication session and the order of applications selected for the application sequence depends, at least in part, on one or more dynamic parameters. The consideration of dynamic parameters for application sequencing provides a more flexible alternative to traditional application sequencing based on static parameters, like user identities. | 02-19-2015 |
