You will want to use sendevent with a unique-id header and a eavesdrop-command header.  Also please note you will want to use svn revision 15175 or later, I just fixed a segfault in that code.

Thanks, Mike, for idea. But what is the syntax for this session message?
I tried this:

sendmsg e8e4f0ed-a0cc-4dff-b7e1-09eeade5df05
eavesdrop-command: 1

but it doesn't work.

There is an event you can send as well to switch them, it your trying
to switch it via event socket, that should be better, its not on the
wiki, but

a session message with
eavesdrop-command header with data as the same as dtmf
should do the trick

But both A and B couldn't hear me.
Btw, after I had send dtmf "1" manually from my phone. B started to
hear me.
There was this record in log:
2009-10-18 03:47:55 [DEBUG] switch_rtp.c:1767 switch_rtp_dequeue_dtmf
() RTP
RECV DTMF 1:2240

Does anybody know, what had I done wrong?

The wiki has a pretty good explanation of how eavesdrop works.
Enabling a talk path to A or B or both A and B requires dtmf.

So, if C hits the 1 button on the phone they can talk to the UUID you
bound the eavesdrop to.   2 talks to the other party.  3 talks to
both
parties.

http://wiki.freeswitch.org/wiki/Misc._Dialplan_Tools_eavesdrop

Adding more api calls to control eavesdrop via event socket should be
possible, though I haven't looked at the code to see what it would
take...

As I've understood eavesdrop allows C to hear A and B, but A and B
will
not
hear C. But in my case B SHOULD hear C. In my case A - client, B -
agent
worked with client and C - coach/supervisor for B. Can I make such
conference in FS using eavesdrop or other API command?

Look at eavesdrop on the wiki.

HI all,



I want to configure FS to make special conference call between three
users
(A, B, C).  In this conference C will hear A and B, but A will
hear only
B.
Can I make it using FS API commands? Does anybody know which
approach is
better to use?

Thanks, Nikita
