Abstract: Establishing or reestablishing media streams for handover of calls in a communication network where the server in the network can be addressed by the client from the access points of the network and for establishing a direct media path between endpoints in different network segments, which are interconnected by servers integrated with gateways.

Abstract: This disclosure pertains to establishing or reestablishing media streams for interception and decryption of media traffic in a service using fingerprint to protected against man in the middle attacks.

Abstract: A telecommunication device for real-time communication at a border between a global transport network and a private domain of a communication network may include a proxy for a communication protocol, means for traffic using real-time communication protocols to traverse a firewall, means for real-time traffic initiated by the communication protocol to traverse a firewall, means for measuring and collecting value information about the real-time traffic over the global transport network, means for creating mutual trust between the telecommunication device and a second device with which it communicates; and means for authorizing usage of a feature for a mutually trusted communication participant.

Abstract: A media path is established or reestablished between real time communication endpoints with one or more network interfaces (194) of different types connected to network access points (140) at different types of network segments (104, 106, 108) to implement handover of calls by collecting, by an RTC device (200), addresses (120) to a server (210) from access points (140) at the network segments (104, 106 and 108). Messages (164) are sent repeatedly by the RTC device (200) to an address (120) of the server (210) and, if not receiving a response, then other collected addresses (120) are tried until a response is received and signaling connectivity is recovered. After recovering signaling between the RTC device (200) and the server (210), a connection identity is presented to the server (210) for recovering the specific connection, after which a media path can be reestablished if needed.

Abstract: A telecommunication device for real-time communication at a border between a global transport network and a local area network may allow traffic using real-time communication protocols to traverse a firewall, classified real-time traffic over best effort traffic for prioritization over the global transport network, measure and collection information about an application, its usage and prioritization used over the global transport network, create call detail records that can be used by a service provider for billing purposes; and deliver the call detail records to the service provider.
