A network-based system and method for providing anonymous voice communications using the telephone network and data communications links under the direction of a Call Broker and associated network elements. A user (the call initiator) present in a text chat room session establishes a data connection to Call Broker and, after qualifying for access (e.g., using credit card information) and providing a callback number, receives voice session information and participant access codes for each desired participant in a voice call. The initiator causes session information and participant codes to be passed to one or more selected chat participants in the current text chat room. When a selected participant uses the received session information, and enters the received participant code and a callback number, the Call Broker in cooperation with a Network Adjunct Processor (NAP) completes voice links to the initiator and the selected participant(s). The need for each party to have a second subscriber line is advantageously avoided by having the Call Broker arrange to have one or more voice links completed through a VoIP link, and further reduces the need for second lines for participants by forwarding a Call Broker—placed call to a busy participant line to the participant's Internet Service Provider (ISP), which then sends a message to the participant announcing one or more options for receiving the incoming call, including receiving the incoming call through a VoIP link.

A power line communication system communicating over a medium voltage power line including a VoIP endpoint that transmits voice data and requests to establish a voice connection to a medium voltage (MV) access device is provided. The medium voltage access device may determine a response to the request, allocate voice data packets a higher priority than general data packets, and transmit the data packets over the MV power line according to their priority. The MV access device may provide one or more voice over internet protocol (VoIP) switch functions and, in response to the requests, grant or deny the requests based, for example, on the number of established voice connections.

Methods and apparatus for selecting a wireless communication network based on quality of service criteria associated with an application are disclosed. In one illustrative example, one of several different software applications of a mobile communication device is executed. The software application may be, for example, an e-mail application, an Internet data application, a voice-over-IP application, a video player application, an audio player application, or a video game application. Each software application is associated with different quality of service (QoS) criteria for data communications through a wireless network. The quality of service criteria may include, for example, a bandwidth criterion, a delay criterion, a delay variation criterion, and a data loss criterion. A scanning operation is performed to identify a plurality of a wireless networks available in a coverage area of the mobile device. One of the identified wireless networks is selected for communication based on a match between its available quality of service and the quality of service criterion associated with the executed software application. Advantageously, the most suitable network may be chosen and utilized for each software application.

The invention relates to a method for creating alternative routes to primary connections, particularly to voice-over IP connections, in which the data transmission occurs in a primary network, and an alternative data transmission occurs in a, as a rule, less efficient secondary network. According to the invention, a system architecture with geographically distributed gateways can be used, said gateways being controlled by a central call processing server. In the event that a disturbance of a signaling path of the communications connection of the primary network is detected, an alternative connection for the signaling path is established via the secondary network, the signaling path of the primary network is logically linked to the created signaling path of the secondary network, and connection data, which were made available by means of the signaling path of the primary network, are made available for the signaling path of the secondary network.

The system of the present invention provides systems and methods for selling goods and services on, over, through, and in conjunction with the Internet. The system receives session (clickstream) information on a customer's website session from the enterprise's website and may also receive customer information on the customer from the enterprise's CRM or eCRM system. The session information referred to comprises the goods or services the customer is searching and metadata about such search and the relevant products, such as the surfing pattern itself. The system determines from the received information, based on the interaction between matching rules created using the system by the enterprise and the system's matching engine, whether the customer is a candidate for assistance from a sales associate. The system creates and indexes information on available sales associates and their performance, selling capabilities and product expertise. The system further matches the customer with at least one sales associate, ideally the most appropriate sales associate, based on the customer, session, and sales profile associate information, and facilitates communication between the sales associate and the customer. Additionally, the system provides information on the customer, products or services the customer is interested in, and the collateral sales materials (both internal and external to the enterprise) and selling techniques to the sales associate based on the particular sales opportunity. The system facilitates communication between the sales associate and the customer on the basis of chat, voice over IP, email and the public switched telephone network, including the concept of bridging a chat session into a PSTN conference call during which call the sales associate and customer maintain a co-browsing session with regard to the opportunity over the Internet.

Systems and methods are provided for preserving the privacy of data contained in mirrored network traffic. The mirrored network traffic may comprise data that may be considered confidential, privileged, private, or otherwise sensitive data. For example, the data payload of a frame of mirrored network traffic may include private Voice over IP (VoIP) communications between users on one or more networks. The present invention provides various techniques for securing the privacy of data contained in the mirrored network traffic. Using the techniques of the present invention, network traffic comprising confidential, privileged, private, or otherwise sensitive data may be mirrored in such a manner as to provide for the privacy of such data over at least a portion if not all of the mirrored communications between the mirror source point and the mirror destination point.
