New Revision: 3434

Modified:
   trunk/libminisip/include/libminisip/media/MediaCommandString.h
   trunk/libminisip/source/subsystem_media/MediaCommandString.cxx
Log:

 * Define a new command that enables local audio forwarding/mixing.
 
   With this implemented, it is simple to implement conferencing with
   audio forwarding (as opposed to the full mesh implemented in the CSD
   course some time ago).

   Example (the first argument is ignored, and all calls in the Minisip
   instance is mixed):

     CommandString c("", MediaCommandString::audio_forward_enable);
     handleCommand("media",c);

   Note that this commit only defines command, and the mixing is not
   commited here.
