摘要： A bridge for multi-network communications is provided. A voice bridge includes an open settlement protocol (OSP) compliant interface for establishing inter-domain voice connections. The voice bridge facilitates connections between OSP compliant and non-OSP compliant networks and interfaces with an OSP server. A call set-up component processes requests from OSP compliant and non-OSP compliant networks. An OSP interface facilitates OSP compliant reporting to the OSP server. Other embodiments comprising additional features, such as address masking, are also provided.

摘要： An apparatus and method for increasing available ports on a voice router is provided. A first gateway and a second gateway are assigned a single port number for a data stream, the direction of packet flow is identified to determine a destination gateway. The destination gateway is one of the first and second gateways, depending on the direction of the packet flow. The packets are then forwarded to the destination gateway. The voice router can further consolidate RTCP streams from a plurality of gateways into a single port on the voice router.
摘要翻译：提供了一种用于增加语音路由器上的可用端口的装置和方法。第一网关和第二网关被分配用于数据流的单个端口号，分组流的方向被识别以确定目的网关。目的网关是第一和第二网关之一，取决于分组流的方向。然后将数据包转发到目标网关。语音路由器可以进一步将来自多个网关的RTCP流合并成语音路由器上的单个端口。

摘要： A network address translation apparatus and method within a Voice over Internet Protocol (VoIP) router is described. This apparatus and method operates within networking devices such as routers, switches, bridges, etc. These devices masks both source and destination addresses and may either replace or complement a firewall in providing security. According to one embodiment, network type information, corresponding to the gateways within connection, is embedded in a port number within a packet header. This network type information is extracted and analyzed to identify the network types of both gateways within the connection. According to another embodiment, a port number is assigned according to the network types of both gateways within a connection. Thus, this network type information may be identified by processing the port number on which a packet is received.
摘要翻译：描述了网际协议（VoIP）路由器内的网络地址转换装置和方法。该装置和方法在诸如路由器，交换机，网桥等的网络设备中操作。这些设备掩盖源地址和目的地址，并且可以在提供安全性时替换或补充防火墙。根据一个实施例，对应于连接中的网关的网络类型信息被嵌入在分组报头内的端口号中。提取和分析该网络类型信息以识别连接中的两个网关的网络类型。根据另一实施例，根据连接内的两个网关的网络类型分配端口号。因此，可以通过处理接收到分组的端口号来识别该网络类型信息。
