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。
