Can someone please help with this. After an outside caller has been parked, they inherit our abilitites to transfer. I have played with all the different combinations of T and t, but nothing seems to work. I found a way to get my Sipura to work with a flash transfer. So right now I am stuck. Is there any way to block callers that have been parked from being able to park us. The only time that this happens is after the call has been parked. Plase help! Im at a loss and people here want answers.
