[Freeswitch-users] "barge in" implementation with mod_socket and eavesdrop

[Artem Shiyanov]

Anthony,
thank you much, "three_way" is a powerful app!
I've added small description in wiki, if you don't mind.
    http://wiki.freeswitch.org/wiki/Misc._Dialplan_Tools_three_way

Meanwhile, another question has been evolved:
In words of the scenario below, now if A hangs up the call then all other
(B, C) channels also being hanged up automatically by FreeSwitch. Is there
any way to save the call B <--> C if A has hanged up the phone? Again, the
whole scenario is the same as it is described in my first message.


Artem
