Abstract: A system and method for teleconferencing between conferees connected through a connectionless network and conferees connected through a connection-oriented network having a bridge. A call server connects to a bridge hosting a teleconference among connection-oriented conferees and joins the teleconference. The connection-oriented signal received by the call server is converted into a connectionless signal and sent to authorized, authenticated conferees connected through the connectionless network. The call server receives a connectionless signal from a conferee through the connectionless network, converts the signal to a connection-oriented signal and sends the connection-oriented signal to the bridge. Connectionless signals are stored in a database to be analyzed or sent to other conferees, such as those who were unavailable to join the teleconference as it occurred. The call server provides multimedia interfaces to conferees by which the conferees can monitor and join an ongoing teleconference, access a stored teleconference, or configure a new teleconference. The call server can also bridge teleconferences hosted on two or more bridges, expanding the audience for a given teleconference beyond the capacity of a single bridge.

Abstract translation: 用于通过无连接网络连接的与会者之间的电话会议的系统和方法以及通过具有桥接器的面向连接的网络连接的与会者。 呼叫服务器连接到在面向连接的与会者之间承载电话会议的桥，并加入电话会议。 由呼叫服务器接收的面向连接的信号被转换成无连接信号，并发送给通过无连接网络连接的授权的认证参与者。 呼叫服务器通过无连接网络从与会者接收无连接信号，将信号转换为面向连接的信号，并将面向连接的信号发送到网桥。 无连接信号存储在数据库中以进行分析或发送给其他与会者，例如那些不能在其发生时加入电话会议的人员。 呼叫服务器向与会者提供多媒体接口，通过该接口，与会者可以监视和加入正在进行的电话会议，访问存储的电话会议或配置新的电话会议。 呼叫服务器还可以桥接在两个或多个桥接器上托管的电话会议，扩展给定电话会议的受众超出单个桥的容量。
