They are talking

The unconfirmed report said the negotiations were conducted last weekend between Iran’s ambassador to Jordan, who was in one hotel room in Amman with Iranian security personnel, while in the next room there were senior Israeli security officials, including the deputy head of the Mossad. The report said a Jordanian mediator carried messages between the sides.
Elaph sources said that "the talks with the Israelis were related to fighting in Syria and the nearing campaign in southern Syria, particularly in Dera'a and Kuneitra." 
Furthermore, they said that Israel made clear to the Iranians not to become involved in fighting close to the Israel-Syria ceasefire lines in the Golan and the Israel-Jordan border. One participant of the talks said that "the sides discussed this issue with the Israelis, and arrived at a quick agreement that even surprised the Israeli representatives."

Let me add one proviso, both sides need to agree that Bolton has to go. Offer Trump a hotel if need be.  If the US is stuck with Bolton, we will blame Israel.
