Abstract: Systems, methods, and computer program products are provided for manual ring-down communication using Session Initiation Protocol (SIP). A first SIP user agent transmits a message to a second SIP user agent over an Internet Protocol (IP) network to establish a SIP session. The first SIP user agent determines that a signal key associated with a first communication device has been selected and transmits, to the second SIP user agent over the IP network, a start event message to cause a second communication device to activate an alert. The first SIP user agent determines that the signal key has been released and transmits over the IP network an end event message to deactivate the alert. The first SIP user agent transmits, to the second SIP user agent over the IP network, one or more subsequent INVITE messages at a predetermined repetition rate to refresh the SIP session.

Abstract: Systems, methods, apparatus and computer program products are provided for sharing a resource including a subscription engine configured to subscribe to a first turret system to share the resource, a state change engine configured to receive a state change notification corresponding to the resource, from the turret system, and a failover engine configured to invite the turret system to initiate a connection to the resource.

Abstract: A personal computer and a telephony device are integrated using an input director and an input receiver. The input director is configured to receive an instruction from a user interface device, the instruction corresponding to a function of the telephony device. The input receiver is configured to receive the instruction from the input director and control the telephony device based on the instruction.

Abstract: Systems, methods, and computer program products are provided for controlling calls and monitoring resource status for turret systems. A SIP message including at least one of a header field and an event package is received from a SIP user agent over a communication network. The header field includes a first parameter corresponding to a first call feature and the event package includes a second parameter corresponding to a second call feature. At least one of the first call feature and the second call feature is implemented by the softswitch or a SIP-enabled turret in response to the receiving.

Abstract: Systems, methods, apparatus and computer program products are provided for sharing one or more resources across a turret system and a telephone exchange including an agent. The agent is configured to register into the telephone exchange as a predetermined device and to receive a state change notification of a resource from at least one of the telephone exchange and the turret system. Receipt of the state change notification causes the agent to change a state of a corresponding resource.

Abstract: A communications system including a turret switching system constructed to communicate to a Web server, a turret device, and to a remote communications device via a first communications network, the Web server being constructed to communicate to a client device via a second communications network, and the client device constructed to control switching across a plurality of lines.

Abstract: A converged services platform based on a hybrid switching architecture in which either a traditional switching model or a soft-switching model may be selected on a call-by-call basis. In addition, the assigned switching model may be dynamically changed while a call is in progress in order to gain access to desired media services while avoiding network latencies and undesirable service delays.

Abstract: An Open SIP Protocol Stack provides a variety of functions within a SIP-based telecommunications network. A set of cooperating layers including a transport layer, a transaction layer and a transaction user core layer. Various processes in these layers index into an associated configuration database designed in accordance with the present invention. The configuration database includes plurality of “mini-stacks.” When a particular transaction is being processed by one of the layers of the Open SIP Protocol Stack, PPL state machines that are to be utilized for that process are “loaded” with the appropriate information from the mini-stack for that attribute. Techniques for transaction processing and editing state machines are also provided by the Open SIP Protocol Stack of the present invention. The Open SIP Protocol Stack may be deployed in a SIP/PSTN gateway, a SIP Application Server, a SIP Media Server, a SIP Redirect Server and a SIP Registrar.

Abstract: A media resources card for use with a converged services platform. The media resources card, which includes one or more arrays of digital signal processors (DSPs), s operable to perform a variety of communication services including recording and playback of voice recorded announcements. A caching arrangement is provided in which a given recording (file) may have either a persistence level or timer expiration attribute or both.
