The method can include transferring the routed emergency call to a predetermined public service answering point based on the identifier.

Abstract: A system establishes a telephone call between a calling party and a called party. The system receives a telephone call connection request, including identification of the called party, from the calling party and determines, based on the identification information, if the called party is currently connected to a data network. If the called party is currently connected to the data network, the system establishes the telephone call between the calling party and an instant messaging client of the called party.

Abstract: A network architecture in accordance with the present invention includes a communication network that supports one or more network-based Virtual Private Networks (VPNs). The communication network includes a plurality of boundary routers that are connected by access links to CPE edge routers belonging to the one or more VPNs. To prevent traffic from outside a customer's VPN (e.g., traffic from other VPNs or the Internet at large) from degrading the QoS provided to traffic from within the customer's VPN, the present invention gives precedence to intra-VPN traffic over extra-VPN traffic on each customer's access link through access link prioritization or access link capacity allocation, such that extra-VPN traffic cannot interfere with inter-VPN traffic.

Abstract: A method and system for providing quality of service in an IP telephony session between a calling party and a called party establishes a high quality of service ATM virtual circuit for the session between first and second devices, each of the devices having ATM capability and IP capability. The first and second devices provide bidirectional translation between IP media and ATM media. The system transports IP media for the session between the calling party and the first device, and between said called party and a second device. The virtual circuit transports ATM media for the session between the first and second devices. An intelligent control layer provides IP and ATM signaling to set up the session.

Abstract: A messaging device may include a memory configured to store a first message from a first caller and intended for a called party and to store information identifying a group that includes a number of broadcast parties that include the first caller. The messaging device may include a processor configured to receive a reply message from the called party and to broadcast the reply message to at least a subset of the group.

Abstract: An approach provides interdomain traversal to support packetized voice transmissions. A request for establishing a voice call is received from a source endpoint behind a first network address translator of a first domain, wherein the request specifies a directory number of a destination endpoint within a second domain. A network address is determined for communicating with the destination endpoint based on the directory number. Additionally, existence of a second network address translator within the second domain is determined. If the network address can be determined, a media path is established between the source endpoint and the destination endpoint based on the network address to support the voice call.

Abstract: A system may include a plurality of components including a voice portal, a web center unit, an Internet Protocol Communications unit, a backbone network service unit, a network interface, an operational data store, and a process management system to connect the plurality of components.

Abstract: A method of routing a telephone call includes receiving an indication, at a handset device 112, to initiate a telephone call. It is then determined, preferably by the handset device 112, whether the telephone call is an emergency services telephone call. If the telephone call is not an emergency services telephone call, it is routed to a proxy server 134. On the other hand, if the telephone call is an emergency services telephone call, it is routed to a local gateway 116 without first accessing the proxy server 134.

Abstract: A Session Initiation Protocol (SIP) device includes one or more voice ports configured to provide voice services; one or more data ports configured to provide data services; firewall logic configured to filter incoming traffic; and quality of service (QoS) logic configured to provide QoS services for traffic transmitted from the SIP device.

Abstract: A double firewalled system is disclosed for protecting remote enterprise servers that provide communication services to telecommunication network customers from unauthorized third parties. A first router directs all connection requests to one or more secure web servers, which may utilize a load balancer to efficiently distribute the session connection load among a high number of authorized client users. On the network side of the web servers, a second router directs all connection requests to a dispatcher server, which routes application server calls to a proxy server for the application requested. A plurality of data security protocols are also employed. The protocols provide for an identification of the user, and an authentication of the user to ensure the user is who he/she claims to be and a determination of entitlements that the user may avail themselves of within the enterprise system.

Abstract: System and method for providing applets to remote devices in a communications network. A preferred embodiment includes a host device, which is the device from which the applet will be transferred, and a target device, which is the device to which the applet will be transferred. In one embodiment, the host device autonomously determines that an applet is to be pushed to the target device. The host device then determines the address of the target device and transmits the applet to the target device. Instructions and commands may be sent to the target device form the host, and the target device may transmit results to the host device. In another embodiment, the target device is customer premise equipment and/or a user device that requests an applet from the host device. The target device requests applets, for example, to perform service parameter verification, performance monitoring, troubleshooting, or the like.

Abstract: A first signal is received from an initial quantum key generating transmitter via a single combined channel that includes a first quantum signal and a public data signal alternating in a time shared manner. The first signal is split into first and second split signals. A low attenuation is applied to the first split signal when the first split signal includes the first quantum signal. A high attenuation is applied to the first split signal when the second split signal includes the public data signal. The first split signal is received at an intermediate quantum key generating receiver (QKGR) when the low attenuation is applied and a first quantum key is generated. A second quantum signal is transmitted to a recipient QKGR and a second quantum key is generated. The first quantum key is encoded using the second quantum key and transmitted to the recipient QKGR.

Abstract: An intelligent policy server provides multiple service features and controls bandwidth usage in an ATM network. Signaling messages generated at an edge switch prior to establishing an end-to-end switched virtual circuit are intercepted by a signaling intercept processor for effectuating policy features or permissions by executing appropriate service logic at the policy server associated with the edge switch. A return message from the policy server determines whether a call connection can be made through the network. Profile arrays are provided which define feature authorizations and provisioning for subscribers and Customer Logical Ports served by the edge switches.

Abstract: A system enables monitoring a multicast data feeds over a network. The system may include a multicast-enabled network device for transmitting a multicast feed from a multicast feed source to a user device via a computer network. A feed agent may be operatively coupled to the multicast-enabled network device for collecting and storing multicast feed data from the multicast feed source. A management server may be operatively connected to the feed agent for receiving multicast feed data collected by the feed agent. The management server may include a web server for receiving requests for multicast feed data over the network via a web interface.

Abstract: An integrated series of security protocols is disclosed that protect remote user communications with remote enterprise services, and simultaneously protect the enterprises services from third parties. In the first layer, an implementation of the Secure Sockets Layer (SSL) version of HTTPS provides communications security, including authentication of the enterprise web server and the security of the transmitted data. The protocols provide for an identification of the user, and an authentication of the user to ensure the user is who he/she claims to be and a determination of entitlements that the user may avail themselves of within the enterprise system. Session security is described, particularly as to the differences between a remote user's copper wire connection to a legacy system and a user's remote connection to the enterprise system over a “stateless” public Internet, where each session is a single transmission, rather than an interval of time between logon and logoff, as is customary in legacy systems.

Abstract: A device may include logic configured to receive a first speech input from a party, to compare the first speech input to a second speech input to produce a result, and to determine if the party is impaired based on the result.

Abstract: A system and method for providing alternate dedicated connections are described. A primary dedicated connection may be configured to connect a first network and a second network, and a second dedicated network-based connection, which may include a point-to-point protocol (PPP)/layer 2 tunneling protocol (L2TP) tunnel, may be configured to automatically connect the first network and the second network when the primary dedicated connection fails.

Abstract: An apparatus and method for performing automated testing and trouble isolation of a communications link in an access network is described. Communications link testing may occur without taking the communications link out of service for the duration of the test.
