    摘要: 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.

    摘要: 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.

    摘要: 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.
