A packetised data network includes IP telephones (ITs) and a network intelligence (NI). All of the keys of each IT are 'soft' keys (i.e., they have no fixed function). The NI associates a configuration data structure with the IT which correlates the keys with functions, and, based on this, may control the display of the IT to indicate the current function of certain of the soft keys. Some of the functions are requests for data services at the telephone (e.g., video or programmed audio over the internet). When a user requests such a service with a key press, the NI sets up the service between the data source and the telephone. This may require associating a new configuration data structure with the keys of the IT. The IT user may activate multiple data services through the NI.

Telephony and data network services at a telephone

A method, apparatus, and article of manufacture for controlling the call control, service control, and user interface functions of a legacy telephone system from a web application. The web application communicates with a legacy call server and controls the legacy call server. A web application also communicates with a legacy telephony device and controls the legacy telephony device. A communication channel may be provided between the web application and the legacy call server, and data transferred over the communication channel is translated to a form that each can understand. The data may be a call control command or a service control command. A communication channel may be provided between the web application and the legacy telephony device, and data transferred over the communication channel is translated to a form that each can understand. The data may be translated to a legacy telephony device data format, and to a web API data format. An abstraction may be used to represent a telephony device or a class of telephony devices having similar characteristics. Access to the telephony device may be arbitrated, and data from the telephony device may be routed. A service plugin may be provided as an interface to the web application. An execution environment may be provided to allows dynamic insertion of service plugins. The data being transferred may be mapped to a telephony device resource. The web application may be an interface to another telephony device, so that telephony devices can communicate peer to peer.

Method, apparatus and article of manufacture for web-based control of a unified multi-service communication system

A circuit and method is described enabling a telephone having two or more lines to have the capability of initiating two simultaneous calls, where there is two-way communication on one of the calls (the collaborating call'), and active monitoring of the second call (the 'teleconference'). A router is used so that the outbound audio signal of the user can easily be switched between the teleconference and the collaborating call. At all times, the transmit path of one of the calls is muted to ensure privacy of the other call.
