Abstract: An approach for processing voice calls over a packet switched network (105) as to efficiently utilize the functionalities of a Voice Response Unit (VRU) (113). According to one embodiment, a call originator (101), acting as a Use r Agent Client in accordance with the Session Initiation Protocol (SIP), issue s messages to establish a first call-leg with the VRU (113). The VRU (113) performs digit collection to obtain information to authenticate the call originator (101) and to authorize the voice call. Based upon the issued messages from the call originator, the VRU establishes a second call-leg wit h the call terminator. The VRU is released from the voice call after binding t he call-legs to connect the call originator to the call terminator (103).

Abstract: An approach for providing mirror servers (101, 103) of a primary server (109 ) to enhance efficient retrieval of web information is disclosed. A primary server (109) communicates with one or more secondary servers (i.e., mirror servers) (101, 103); the primary server (109) and the secondary servers (101 , 103) communicate with each other over a communication network (105), such as the public Internet. A user station (107) initially communicates with the primary server (109) to retrieve information. The primary server (109) determines a particular secondary server (101 or 103) based upon network analysis data. The network analysis data may optionally be stored as a cooki e in the user station (107). Thereafter, the primary server (109) instructs th e user station (107) to communicate with a particular secondary server (101 or 103) for subsequent requests. The secondary server (101 or 103) is selective ly synchronized with the primary server (109).

Abstract: A method, system, and computer program product for controlling customer resources for Internet protocol (IP) traffic delivery are disclosed. The network utilization of a group of endpoints on a network is tracked to generate group utilization level information corresponding to a current amount of network resource consumption by the group of endpoints. A request for network resources for a data flow for an endpoint in the group is received from a router associated with that endpoint. The request for network resources includes an identifier associated with the endpoint. A determination is made whether to accept the request based on the group utilization level information, the identifier, and a first predetermined profile associated with the group and including a first network utilization limit.

Abstract: A system and method for routing a telephone call (10) on a PSTN network (14) to a data device (18). The present invention utilizes an automatic call processing system that has a one number location service. A called party provides a calling profile that is stored in the automatic call processing (ACP) system (16). When a call is placed to a telephone number that is assigned to the called party, the call is routed to the ACP system (16). The ACP system (16) calls each of the numbers of the calling profile for that called party until that party is reached. At least one of the destinations i n the calling profile is a logical address for a data network. The automatic call processing system (16) recognizes the logical address and queries a directory (22) to determine if an IP address has been registered in the directory for the logical address of the called party. If the called party i s using a data device (18) that is logged on the Internet (20), an IP telephon y agent (19), such as an IP telephony client running on the data device (18), registers the IP address of the data device (18) together with the logical address of the caller. If the ACP system (16) determines if an IP address is registered with the directory (22), the ACP system (16) will direct the call to an Internet telephony gateway(28). The gateway (28) encodes and packetize s the voice information for transmission over the data network (20) to the dat a device (18).

Abstract: A call forwarding system (10) that prevents unwanted call forwarding activations from taking place. The system (10) requests approval prior to activating call forwarding. The approval is obtained by sending a request communication to the destination (20) to which calls are to be forwarded. Th e destination (20) has the option of accepting the request for call forwarding or rejecting the request. The call forwarding may be applied to phone calls between electronic devices and to video communication sessions over computer networks.

Abstract: A system and a method are provided for processing and routing electronic mail messages within a call center which include and involve an electronic mail server system for routing incoming and outgoing electronic mail messages and a mail parsing system coupled to the electronic mail server system. The mail parsing system is operative to receive an incoming electronic mail message from the electronic mail server system, to automatically parse the incoming electronic mail message for the existence of at least one predetermined term related to a particular call center activity, and to route the incoming electronic mail message via the electronic mail server system to a corresponding storage area when the incoming electronic mail message contains at least one predetermined term.

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 virtual private network (31) includes an internet protocol (IP) network (4 7) and a public switched telephone network (PSTN) (37). An enterprise gateway (55) is operably connected to the IP network (47). The enterprise gateway (6 1) is operably connected to a switch (33) of the PSTN (37) through a direct access line (DAL). The set-up signaling for virtual private network (31) cal ls and the calls themselves are transported across the internet protocol networ k (47) and the public switched telephone network (37) through the direct acces s line.

Abstract: A state-of-polarization (SOP)-independent device (226, 326) and method for determining polyrization mode dispersion (PMD) in an optical communication system having an optical transmission line (224, 324), including a detector (244, 344), coupleable to the optical transmission line (224, 324), where th e detector (244, 344) is capable of analyzing a pulse shape of an optical sign al on the optical transmission line to determine PMD of the optical signal. A corrector (246, 346) may be coupled to the detector (244, 344), where the corrector (246, 346) is capable of compensating the optical signal for the determined PMD. A controller (242, 342) may be coupled to the detector (244, 344) and the corrector (246, 346). The pulse shape may comprise an eye diagram, which may contain a first peak and a second peak, due to PMD, where the PMD determined by the detector (244, 344) is a function of the distance between the detected first and second peaks which is indicative of a time delay between the detected first and second peaks. The device and method may also include a verifier (348) coupled to the corrector (246, 346), where the verifier (348) is capable of verifying that the corrector (246, 346) correct ly compensated the optical signal for the PMD.
