I'm sorry Benjamin, Barack's not talking to you 

Don't you hate it when best friends have a falling out?

Obama would pretty much guess what the phone call was about, either funding or Iran.

Netanyahu denied meeting with Obama after lashing out at US

The White House has shot-down a request from Israeli Prime Minister Benjamin Netanyahu to meet with US President Barack Obama later this month, a rejection that comes right after an unusually hostile statement directed towards the United States.

Prime Minister Netanyahu is not expected to meet with Mr. Obama later this month when the Israeli PM comes stateside to visit the United Nations in New York City, despite a plea recently extended to the White House. Reuters report that Netanyahu’s office had requested a meeting with the American commander-in-chief, but that staffers for the president don’t seem interested in entertaining the idea.
"[T]he White House has got back to us and said it appears a meeting is not possible. It said that the president's schedule will not permit that,” an Israeli official tells Reuters on condition of anonymity.

Washington has denied that they flatly refused Israeli PM Netanyahu's request for a meeting and that a scheduling conflict was the catalyst in the decision. On the heels of a series of publicized disagreements between the two allies, however, the rejection is being seen by some as a response motivated by something much different.
