A method of diverting a hunting function of a PSTN central office switch is provided. The method diverts a hunting function in the event a channel within a hunting group is available but a call can not be completed. The method comprises detecting a status of a plurality of user channels to determine whether all user channels associated with the hunting group are in use and providing a hunting diversion message to the PSTN central office switch in response to determining that all user channels associated with the hunting group are in use. The method also comprises detecting at least one user channel associated with the hunting group is available for an inbound call and providing a hunting enable message to the PSTN central office switch in response to determining that at least one user channel associated with the hunting group is available for an inbound call.

A directory server provides a media session channel for communication of real time streaming media data from a remote client to a client served by an address translation firewall. The directory server includes a client registration module for receiving a registration datagram originated by the client, source network address and a source port number from the registration datagram, and providing a session signaling message from the remote client to the client utilizing the extracted source network address and source port number.

A network access module interconnects a stand alone multi-media terminal adapter with a network controller of a frame switched network. The network access module comprises a frame switched network interface coupled to the frame switched network for communicating with the network controller. The network access module further comprises a communication link interface for communicating with the stand alone-multi media terminal adapter. A service flow module is coupled to the frame switched network interface and coupled to the communication link interface. The service flow module receives a plurality of frames of IP traffic from the multi-media terminal adapter and sorts the frames such that each frame is delivered to the frame switched network interface at a time that corresponds to a time division logical channel which corresponds to the frame. A QoS module is coupled to the service flow module and coupled to communication link interface. The QoS module generates a quality of service request for transmission to the network controller in response to receipt of a bandwidth management instruction from the multi-media terminal adapter.

A stand-alone multi-media terminal adapter controls a dynamic quality of service management system of a broad band network access module. The multi-media terminal adapter provides the dynamic quality of service management system with instructions to reserve, commit, and release time division logical channels on a broad band network as well as discrimination identification to be used by the network access module for identifying IP traffic that corresponds to a time division logical channel. The multi-media terminal adapter receives acknowledgement of a time division logical channel that comprises identification of a frame frequency and a frame size. The multi-media terminal adapter encapsulates compressed digital audio data representing a VoIP session into IP frames with a frame size, frame frequency, and discrimination identification that corresponds to the time division logical channel.

The improved AES processing method provides an efficient alternative to both Mips intensive multiplication and to conventional table lookup, used to multiply terms over a Galois field (GF). The improved method takes advantage of the fact that in the GF, any non zero element X can be represented by a power of a primitive element P. The improved method thereby results in a 2 by 256 table. The log base P of the terms being multiplied are looked up and summed, and the anti-log of the sum is looked up in the same table.

A device provides for sending datagrams representing real time streaming media frames to a client independent of whether the client is served by a network address proxy. The device receives a datagram originated by the client that includes an indicated network address and an indicated port number for receipt of the datagrams representing real time streaming media frames, extracts a source network address and a source port number from the datagram originated by the client, and compares the indicated network address to the source network address. The device addresses the datagrams representing real time streaming media frames to the source network address and source port number if the indicated network address and the source network address are not the same.

A method for communicating real time media data between a first client and a second client across a packet switched data network is provided. The method includes receiving an indication of a first client network address for use as a destination network address for sending media datagrams to the first client. A media datagram originated by the first client is also received. A comparison between the first client network address and a source network address extracted from the media datagram originated by the first client is made. A media datagram is sent to the first client using the source network address if the source network address and the first client network receiving address are not the same and the media datagram is sent to the first client using the first client network address if the source network address and the first client network address are the same.

An IP telephony gateway operates in conjunction with a base station of a hybrid micro cellular wireless telephone network. The base station supports roaming of a wireless telephone into a cell controlled by the base station. The IP telephony gateway comprises: i) a circuit switched network interface for exchanging system messaging, call signaling, and audio media with a circuit switched system controller; ii) a base station network interface for exchanging system messaging, call signaling, and audio media with a base station; and iii) a VoIP client for exchanging system messaging, call signaling and audio media with a remote VoIP device over a packet switched network. A management module interfaces messages exchanged with the base station and each of the circuit switched system controller and the soft switch to support roaming of the wireless telephone into the cell controlled by the base station.

A communication service provider accounting server is used to track communication session usage by a client of the service provider. The accounting server receives an indication identifying a client that has commenced a communication session and an indication identifying that the client has terminated the communication session. The accounting server further provides periodic status request messages to the client and receives a sequence of status response messages in response thereto from the client. The accounting server determines a session termination time as the earlier of receipt of the indication that the client has terminated the communication session and making a determination that the sequence of status messages have ceased.
