Guys, Hold/Unhold, blind transfers is fine without REFER support But... Please note that attended (consult) transfer will not work. I did many tests and MS does 3th call to connect Transferee and Transfer Target. Not sure why. I tried same things from regular softphone - and it works great without 3th call.
