A communications system ( ) is provided which comprises a plurality of network hubs ( ), ( ), and ( ). Network hubs ( ), ( ), and ( ) are interconnected through a communications network ( ). The system ( ) interconnects messaging systems ( ), ( ), ( ), ( ), ( ), ( ), ( ), ( ), ( ) and ( ) having disparate capabilities and using disparate communications protocols. The network hubs use numbers of connection processors ( ) and ( ) to interact with the messaging systems. A hub database ( ) and message store ( ) are used to store control information and messaging information within the network hubs. A network processor ( ) is used to interact with other hubs within the communications system ( ). A message router ( ), connection manager ( ), data replicator ( ), and an administrative event manager ( ) are used to control the operations of-the hub in processing a message. A management server ( ) and a event processor ( ) are used by communications system ( ) to manage the internal operations of each of the network, hubs.

International Classification:

H04M 300

US Classification:

379386, 37914201

Abstract:

For use with analog telecommunications equipment that responds to in-band stimuli, a system for, and method of suppressing an in-band stimulus and a telecommunications infrastructure employing the system or the method. In one embodiment, the system includes: (1) a stimulus detector, associated with the analog telecommunications equipment, that detects a presence of the in-band stimulus and (2) a stimulus suppressor, coupled to the stimulus detector, that alters the in-band stimulus to cause the analog telecommunications equipment to disregard the in-band stimulus.

US Classification:

370217, 370242, 370352, 370401

Abstract:

A high availability VoIP system interfacing with a PSTN or other TDM network to provide higher availability and better failure recovery wherein the high availability VoIP system includes a plurality of gateways coupled to at least one hub and a proxy table and a call restoration table configured in each of the plurality gateways. Further, the present invention is a method of providing a high availability VoIP system wherein the method includes configuring a plurality of gateways between a PSTN and at least one hub of the system, implementing a proxy table and a call restoration table in each of the plurality of gateways, wherein when a call is received by a gateway in the plurality of gateways from the PSTN, the call is divided into a session initiation protocol (SIP) portion and a real time protocol (RTP) portion, and further wherein the SIP portion is sent to a proxy server and the RTP portion is sent to a media server, both being located in the at least one hub and further routed to an endpoint such as a SIP controlled softphone. A further method of the present invention includes routing SIP voice calls through the plurality of gateways using a proxy server priority table.

International Classification:

H04L 12/66

US Classification:

370353, 370354, 370384, 37926505, 37926509

Abstract:

The present invention is a system and method of receiving realtime and non-realtime communications from customers, distributing those communications efficiently to an appropriate agent and providing a response to the communication within an appropriate time. The present invention utilizes a hub and node architecture where realtime communications such as a voice call entering the architecture are received by a Voice over Internet Protocol (VoIP) gateway before being sent to a voice server. Other realtime and non-realtime communications are received by an appropriate media server. Routers for each media type access a predetermined set of routing data with an application server through a corporate and CRM database to facilitate routing through a node router to the appropriate node and agent.

International Classification:

H04M 1/64

US Classification:

379 8817, 379 76, 37926502, 370353

Abstract:

The present invention is a method and system for reducing bandwidth usage in a voice over internet protocol (VoIP) network that uses holding sounds such as music or announcements. When a customer call enters the network through a gateway, the call is received by a media server (VMS) and a workflow is started. When the workflow determines that the customer call is to be put on hold, the VMS sends an instruction signal to the gateway, instructing the gateway to provide an on-hold music or announcement to the customer call. When the workflow determines that the customer call is to be taken off hold, the VMS sends a second instruction signal to the gateway and the gateway stops the music or announcements and proceeds to further process the call under the direction of the workflow.
