Hello!

I'm trying to implement "barge in" functionality (see http://www.yourdictionary.com/telecom/barge-in) with "eavesdrop" but still with no success.

The situation is:
- Person A calls to the extension:
<extension name="some_ext">
  <condition field="destination_number" expression="^900.$">
    <action application="answer"/>
    <action application="park"/>
  </condition>
</extension>

- I bridge him with person B with help of mod_socket:
SendMsg <some_uuid>
call-command: execute
execute-app-name: bridge
execute-app-arg: <person B address in form: "user/...">

- A and B talks

- Person C decides to barge in the call A<-->B (to become a third participator in the call)
a) I send (mod_socket):
SendMsg <C_uuid>
call-command: execute
execute-app-name: eavesdrop
execute-app-arg: <A_uuid or B_uuid, result is the same>

b) Then, as the spec says (http://wiki.freeswitch.org/wiki/Misc._Dialplan_Tools_eavesdrop)
I sent DTMF "3" with
api uuid_send_dtmf <C_uuid> 3
but it doesn't work. I mean that A can hear B and vice verse, but both A and B can't hear C. C also doesn't hear neither A nor B.

If I press "3" on the C's softphone (latest X-Lite) then, really, C becomes a full-capabilities participator of the call.
Instead of "uuid_send_dtmf" I tried:
1)
sendevent DTMF
Unique-ID: <C_uuid>
DTMF-Digit: 3
DTMF-Duration: 2000

2) first make queue_dtmf for the <C_uuid>, and then eavesdrop

3)
SendMsg <C_uuid>
call-command: execute
execute-app-name: gentones
execute-app-arg: 3

4)
SendMsg <C_uuid>
call-command: execute
execute-app-name: send_dtmf
execute-app-arg: 3

And none of these methods leads to the "barged in" call.

Anyone knows how to press "3" programmatically on behalf of the given channel with mod_socket?!

Anthony,

thank you much, "three_way" is a powerful app!
I've added small description in wiki, if you don't mind.

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.

to do that you would have to transfer all the parties into a conference
