Help required for sequence: lineSetupTransfer / lineDial / lineCompleteTransfer



Hallo everybody,

I have problem implementing this sequence.
Working with smartphone WM6.
Using TAPI 2.0 (InitializeEx ->ok, version is required one)

lineSetupTransfer -> Ok
call becomes LINECALLSTATE_OHOLDPENDTRANSFER -> First problem wm6 do
not recognize this call as call OnHold (so I can't unhold using device
buttons)
wait for states -> Ok
lineDial() ->Ok
wait for states-> Ok
lineCompleteTransfer(MODE_TRANSFER) -> ok
wait for states -> fail - calls are not ended and left active,
dropping them drops all calls , but system still "see" active call.

By the way lineBlindTransfer works fine (worst thing I must be sure
call was transfered)
Does anybody has / had such problems. Any ideas welcome.

Thank's and execuse me for my English.
Romualdas
