Genuine question because I'm not really sure... can the Orthodox even call a council?
Historically, only the Emperor could call councils as he is the only one who had the authority and the financial means to call one. He could do it alone and everyone including the Popes legate came as commanded. The Pope himself did not attend as all of the councils were in the east, and that was a really dangerous trip. I think you also were in the possibility of not being Pope when you got back to Rome if you were gone too long.
That was the case of the first seven ecumenical councils, all accepted by the RCC and the Orthodox Church.
Those seven are considered Ecumenical as all of the Churches were in attendance and confirmed the decrees, including the Bishop of Rome/Pope. The Bishop of Alexandria also goes by Pope.
The Bishop of Rome was one of just five patriarchal seats. Rome, Constantinople, Alexandria, Jerusalem, and Antioch.
At times the Roman Bishop was considered a first among equals, but the title was purely honorary. This was often contested by the Patriarch in Constantinople.
In the west, post Schism , the Pope can call a council as he is the only figure to have left the Orthodox Church and I suppose he can do whatever he likes.
Since the fall of the Byzantine Empire, there has been no single emperor or figure with the universally accepted authority to convene a new council of that scale, which is a primary reason no new Ecumenical Councils. We almost had one a few years ago, but I believe a beef between the church in Jerusalem and the Russian church causes it to fall through.
So in short, yes, you can have a council, but you need all of the Patriarchs in agreement. Tough sell as most of the Churches and Patriarchs don't see the reason to call one. I can't think of a reason. They can't all be required to attend as they were in the past by an Emperor and then hash things out.
That's a rambling answer, but I think that's mostly accurate.
