i just want to know how to do that in freeswitch.

    for example, i have two audio conference 3001 and 3002, which  has it's own members in conference ,and now i want all user in the two conference can hear all the talking.

first it may think transfer the member of 3001 to 3002, but it is not want i want, cause if i may link any two conference, and when i cancel such link, the member in the original conferece  was not affected.

  thanks for any clue in advance.
