Methods and systems are disclosed wherein TCP may approximate Reliable Transport Protocol (RTP) or UDP delivery for real-time video/data conferencing applications that have long RTT connections.

Timely delivery of real-time media problem when TCP must be used

A communication device detects sound with a microphone to produce a sound signal representative of the sound and searches the sound signal for unique inaudible sound signatures associated with a group identifier. Each sound signature identifies a respective communication device. Each sound signature is in an audible frequency band but masked to be imperceptible. If any of the sound signatures are determined to be present in the sound signal, the communication device selects one based on predetermined criteria associated with the group identifier.

Detecting proximity of devices based on transmission of inaudible sound signatures in the speech band

Media relay services are often used to establish sufficiently direct connections in order to enable provisioning of a real-time media service and/or improve the quality of real-time media services. However, media relay services are often gated using authentication systems that add undesirable delay to the delivery and/or access to a real-time media service, which in turn diminish the user experience. By contrast, various implementations disclosed herein include apparatuses, systems, and methods of providing low latency authentication of gated media relay services. For example, in some implementations, a method includes receiving a request for access to a gated media relay service, providing provisional access to the service until an authentication result is available, determining whether the requesting device is authorized to access the media relay service, and at least one of ending or continuing access to the media relay service based on the authentication result.

Low latency authentication of gated media relay services

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.

High availability VoIP subsystem

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.

Bandwidth reduction in a VoIP network using music on hold

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.

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.
