Methods for providing contextual information about communication devices and/or services. Profile information indicating a user's communication devices and/or services is stored. When profile information or a message log is displayed, the user may identify a communication device and/or service. A query inquires whether the user would like contextual information. The contextual information may be obtained from a gateway in a data network or a telecommunications manager in a telecommunication network. The contextual information is displayed. Profile information about a user's communicating partner may be stored. When the user makes an effort to communicate with the partner, a check may be made of the partner's profile information for a preferred communication device and/or service. If the user does not have a communication device and/or service corresponding to that of the communicating partner, a query may inquire whether the user would like contextual information. If so, the contextual information is presented.

Telecommunications systems and methods having a mapping server; a communication network; and a mapping database in communication with the mapping server via the communication network, the mapping database associating telephone identifier data strings (which identify a target telephone device) with numeric telephone identifiers; the mapping server is configured to match numeric telephone identifiers of a source telephone of a caller and a target telephone of a callee with respective telephone identifier data strings using the mapping database; the mapping sever is configured to initiate an electronic communication between the source telephone and the target telephone; the numeric telephone identifier of the target telephone is masked to the caller using the target telephone identifier; the mapping server is configured to locate the target telephone device by the telephone identifier data string to provide a Global Positioning System display of the target telephone device on a screen of a source telephone device.

An embodiment of the system for publishing events of a telephony application to a client includes a call router that generates events from the telephony application and an event router that manages the publication of events generated by the call router and that manages the subscription to events by clients. The system can be used with a telephony application that interfaces with a telephony device and an application server

A dynamic communication management system manages the exchange of phone-based communications between devices using dynamically determined routing data. The routing for the phone-based communications can be dynamically determined such that certain identifying information is provided to destination devices instead of the identifying information that would be provided without the services of the dynamic communication management system.

A switching system includes a content-addressable memory (CAM) and several processing nodes. The CAM can be selectively connected to any one or more of the processing nodes during operation of the switching system, without having to power down or otherwise reboot the switching system. The CAM is selectively connected to a processing node in that electrical paths between the CAM and the processing nodes can be established, torn down, and re-established during operation of the switching system. The switching system can include a connection matrix to selectively establish electrical paths between the CAM and the processing nodes.

Methods and systems for routing multimedia traffic are described. A method may include receiving a communication originating from a user, transposing an alias transport network over one or more existing networks to route the communication, and routing the communication based on mapping rules.

A Voice over Internet Protocol (VoIP) server is configured to provide VoIP services to a plurality of VoIP-capable endpoint devices. Geolocation information identifying a first geographic location of the particular endpoint device is received at the VoIP server and from an application running on a VoIP-capable endpoint device. A second geographic location for an IP address is compared to the first geographic location. In response to a mismatch between the compared geographic locations, a location database is modified to include an entry specifying that the particular endpoint device is located at the first geographic location. For an outgoing telephone call from the endpoint device, the modified entry is used to select a telephone carrier. The outgoing telephone call is routed using the selected telephone carrier.
