in the hermitage museum in the walkthrough I have looked around completely now I need to call ostankovic but I get the message I still need to look before I call him because he is serious on his orders so I am unable to call out to him could you please advise where I need to go from here or am I missing something?

HAve you done this part?
Go right to the next room - corridor - Paintings Gallery.
See-look close at barrier set up for Peter the Great's hallway.
Go back to the Vase Gallery and window. Use the cell phone and call Ostankovic. Learn about the barrier and Peter the Great painting.

Thanks MaG:
I had failed to look close at barrier
