| 20090116634 | ACCOMMODATION OF TWO INDEPENDENT TELEPHONY SYSTEMS - Independent telephony systems are integrated by using symmetric forking from both systems. Calls received by either system are forked to the other system. Thus, a call can be accepted by one of the systems, using its external interfaces, and presented to all devices in both systems. Each system is enabled to leverage internal call control advanced features to enhance overall user experience. Internally inserted parameters to call requests are used between the two systems for preventing endless loop of calls between the integrated systems. | 05-07-2009 |
| 20100278322 | USER-BASED AUTHENTICATION FOR REALTIME COMMUNICATIONS - Architecture for a communications system enabling a user to provision a telephone at a new location without network administrative pre-configuring. An input component (e.g., keypad) receives a numeric extension and PIN. The extension is a telephone extension of the user and the PIN can be administratively assigned. A location component provides location information of an enterprise communications server to the telephone based on the extension. The telephone uses the location information to send messages to the enterprise communications server. A registration component registers the telephone with the enterprise communications server based on the numeric extension. A telephony address is returned to the telephone. An authentication component authenticates the telephone based on the PIN. Upon authentication, the extension is assigned to the telephone, and telephone communications can be sent and received from that location. | 11-04-2010 |
| 20110153826 | FAULT TOLERANT AND SCALABLE LOAD DISTRIBUTION OF RESOURCES - A resource is located on a server using a distributed resource algorithm that is executing on each server within a cluster of servers. A request for a resource is received at a server in the cluster. The server executes the distributed resource algorithm to determine the server that owns the requested resource. The distributed resource algorithm automatically adapts itself to servers being added or removed within the cluster and is directed at evenly distributing resources across the available servers within the cluster. | 06-23-2011 |
| 20110299387 | SURVIVABLE AND RESILIENT REAL TIME COMMUNICATION ARCHITECTURE - Enhanced communication systems with various resiliency and survivability aspects are provided. Data center, cluster, network, and load balancer survivability are provided for seamless communication experience in case of data center, cluster, discovery infrastructure, or hardware load balancer failures. Call, data, and authentication survivability are provided through dynamic re-routing over alternative networks, continuous data replication, and alternative authentication mechanisms. Seamless failover is ensured through use of identical signaling protocols and data carried by protocols between primary and backup clusters. Voicemail resiliency is achieved by re-routing calls directed to voicemail over alternative paths such as PSTN connections. | 12-08-2011 |
| 20110307541 | SERVER LOAD BALANCING AND DRAINING IN ENHANCED COMMUNICATION SYSTEMS - Resilient load balancing servers in an enhanced communication system is provided mitigating server failures or scheduled shutdowns. A repeatable but virtually random sequence of servers is generated for a given pool of homogeneous servers based on a user identifier in a request message. If a request cannot be routed to a first choice server, for any reason, then subsequent servers in the sequence are selected. A communication protocol within the system is adapted to permit an individual server to indicate that it cannot accept new requests. Following the indication from the server, traffic associated with existing dialogs is allowed to continue to be processed by the server, but new dialogs are directed to other servers. | 12-15-2011 |
| 20110307587 | DEFINITION CONFIGURATION AND ADMINISTRATION OF DISTRIBUTED SERVER SYSTEMS THROUGH STRUCTURED DATA MODEL - A platform for manipulating data associated with defining, deploying, and administering distributed server systems utilizes a structured data model with a flexible replication mechanism, a set of schemas, and an object model to manipulate system topology, configuration (settings), and policies. A scoping mechanism for characteristics of the settings, policies, and resolution is provided in addition to the data model along with an authorization mechanism for single and multi-tenant environments. | 12-15-2011 |
