Abstract: A communications system that supports multimedia components is easily adapted to existing network elements. Voice components arriving at or coming from a user having multimedia capabilities are referred from a telephony server serving the user to a multimedia server. A determination is made as to whether the other party supports multimedia capabilities. If that determination is negative, the component is passed back to the telephony server with an indication that the session is coming from the multimedia server to avoid an infinite loop. If the determination is positive, a parallel multimedia component is established between the parties while the multimedia server remains aware of the bearer path.

Abstract translation: 支持多媒体组件的通信系统很容易适应现有的网络元件。 从服务于用户的电话服务器向多媒体服务器转发到达或来自具有多媒体能力的用户的语音组件。 确定对方是否支持多媒体功能。 如果该确定是否定的，则该组件被传递回电话服务器，其指示会话来自多媒体服务器以避免无限循环。 如果确定是肯定的，则当多媒体服务器保持知道承载路径时，在各方之间建立并行多媒体组件。

Abstract: In one embodiment, a service node will recognize an attempt to initiate a call from a first terminal to a second terminal, and automatically provide information to media clients associated with the first and second terminals such that a media session can be readily established between the media clients in association with the call. The service node may be configured to interact with telephony switches that support the first or second terminals, directly or indirectly via a signaling adaptor. In a second embodiment, the service node will recognize an attempt to initiate a call and will route the call to a gateway, which is controllable by the service node. Once the call is sent to the gateway, the service node may provide instructions to the gateway for routing or otherwise processing the call.

Abstract translation: 在一个实施例中，服务节点将识别发起从第一终端到第二终端的呼叫的尝试，并且自动地向与第一和第二终端相关联的媒体客户端提供信息，使得可以容易地在媒体之间建立媒体会话 与呼叫关联的客户端。 服务节点可以被配置为通过信令适配器直接或间接地与支持第一或第二终端的电话交换机进行交互。 在第二实施例中，服务节点将识别发起呼叫的尝试，并将呼叫路由到网关，该网关由服务节点控制。 一旦呼叫被发送到网关，服务节点可以向网关提供路由或其他处理呼叫的指令。
