    1616The Audio Conference Bridge 
    17 --------------------------------------------------------- 
     17---------------------------- 
    1818The conference bridge provides a simple but yet powerful concept to manage audio flow between the audio medias. The principle is very simple, that is you connect audio source to audio destination, and the bridge will make the audio flows from the source to destination, and that's it. If more than one sources are transmitting to the same destination, then the audio from the sources will be mixed. If one source is transmitting to more than one destinations, the bridge will take care of duplicating the audio from the source to the multiple destinations.

    6262Looping Audio 
    6363+++++++++++++ 
    64 If you want, you can loop the audio of a media object to itself (i.e. the audio received from the object will be transmitted to itself). For example, you can loop the audio of the sound device with:
