Cannot TRANSFER call

Hi
I cannot succeed in transfering a call. (3rd party application,
Panasonic TDA100 PBX)
I guess if I forget something, even if i do everything Microsoft
samples and msdn told me.

Now I'm usinga TAPI3 Browser.

I initialize tapi, RegisterCallNotification (with EventFilter set) on
the 3 extensions involved.
I can make a call from A to B, and viceversa.
I can put in HOLD state A or B
(the called address , if I call ITBasicCallControl->Hold on the "main
call" I created,
the caller address , if I call ITBasicCallControl->Hold on "the
call seen on the other side", retrieved through
ITCallNotificationEvent.

If I call TRANSFER method (in both cases, call working, or call in
Hold state)
it doesn't fails, but the consultation call doesn't start (the phone
doesn't ring,
and FINISH doesn't work.)
I tried to pick up manually the phone C where I want to transfer the
call, but it is not connected
(I thought "maybe it doesn't ring but it is waiting for me to pick
up")

I see events, but I cannot see "useful" events to be managed when I
try to transfer the call.

Any idea? thanks.
