An apparatus is provided for enabling communication between telephony devices. The apparatus includes a queue operable to receive incoming media packets from the telephony devices, and a payload segmenter coupled to the queue and operable to divide an incoming payload section of each incoming packet into one or more data segments. The apparatus also includes a mixer coupled to the payload segmenter and operable to mix the data segments from the telephony devices to create an aggregate data segment. Furthermore, the apparatus includes a reassembly buffer coupled to the mixer and operable to construct an outgoing payload section for one or more telephony devices by linking successively generated aggregate data segments.

System and method for converting packet payload size

A method is provided for establishing a telephone call between a trusted Internet Protocol (IP) telephone and an untrusted device. The method includes receiving a call initiation request from the untrusted device that indicates a desired communication with the trusted IP telephone. The method evaluates the call initiation request, and establishes a telecommunication link between the untrusted device and the trusted IP telephone in response to a positive evaluation of the call initiation request.

System and method for providing security in a telecommunication network

A system includes telephony devices that provide services and applications through the execution of scripts in web pages.

Extended telephony functionality at end points

Language for implementing telephony processing in end points

A virtual telephony intermediary is provided that includes a first logical port associated with a first telephony device and a second logical port associated with a second telephony device. The virtual telephony intermediary also includes a data manipulation module that manipulates telecommunication data in a payload section of a packet received from the first telephony device at the second logical port. The virtual telephony intermediary further includes a transmission module operable to communicate the manipulated telecommunication data to the second telephony device.

System and method for a virtual telephony intermediary

A method is provided for maintaining media streaming to a telephony device. The method includes establishing a media streaming link between a first telephony device and a second telephony device using a media termination point. The media streaming between the first telephony device and the second telephony device passes through the media termination point. The method further includes receiving a request to implement a telephony feature requiring media streaming termination between the first and second telephony devices. The method also includes terminating the media streaming between the first telephony device and the media termination point while maintaining the media streaming between the second telephony device and the media termination point.

System and method for maintaining a communication link

A system and method for allowing remote control of an isochronous device. The system comprises: (1) first and second isochronous devices, (2) a packet-based signalling channel coupling the first and second isochronous devices and allowing communication of signalling messages between the first and second isochronous devices, the first isochronous device capable of initiating a request to the second isochronous device to transfer multimedia information from the second isochronous device to the first isochronous device and (3) an isochronous user information path established by the second isochronous device in response to initiation of the request, the isochronous user information path coupling the first and second isochronous devices for transfer of the multimedia information, the first isochronous device thereby effecting remote control of the second isochronous device. The present invention further introduces a system for adapting a data stream received into a computer from an isochronous user information path for use by a video file viewing application, such as an MPEG video viewer.

Multimedia client for multimedia/hybrid network

An electronic step-by-step switching system utilizes much of the equipment now present in conventional electromechanical step-by-step telephone exchange switches. Conventional line finders, selectors and connectors are modified by removing the relay logic and replacing it with microprocessor based controllers. The modified line finders communicate through a bus with an originating controller and the modified connectors communicate through a bus to a terminating controller. The controllers are interconnected for data exchange through high speed buses that are supervised by a bus controller. A programmer station is installed for bi-directional communication through the bus controller. The originating and terminating controllers include memory storage for maintaining status information concerning the subscriber lines within the groups of corresponding line finders and connectors. The modified line finder works in conjunction with the originating controller to identify the line for an off-hook subscriber. The line number is translated to a telephone number by the originating controller making possible the addition of functions and revenue features for a local telephone exchange. Likewise, the addition of identifying information about called parties by the storage of information in the terminating controller makes possible the addition of still further features which can be implemented in a substantially conventional electromechanical step-by-step telephone exchange.
