Mr Netanyahu enjoyed a close relationship with Donald Trump, who controversially moved the US embassy in Israel to Jerusalem. However, after more than three weeks in office, the new president has yet to even call the Israeli leader.
Danny Danon, formerly Israel’s ambassador to the UN, raised his concerns on Twitter.
He posted: “Joe Biden, you have called world leaders from Canada, Mexico, UK, India, France, Germany, Japan, Australia, South Korea and Russia.
“Might it now be time to call the leader of Israel, the closest ally of the US?
“The PM’s number is 972-2-670555.”
The number he provided is linked to the Israeli ministry of foreign affairs.
However, when a Guardian journalist called it they got a message saying the line was out of service.
Mr Netanyahu said on Monday he still expects a call and isn’t troubled by the delay.
He said: “He is making calls to world leaders according to the order he sees fit.
“Glad you’re seeing that Netanyahu making Israel an affiliate of the Republican Party has been noticed and has consequences.
“The call will come. But trolling the US President about it won’t help and suggests you’re still not getting the message.”
A similar message was given by David Aaron Miller, a Middle East specialist who used to work at the state department.
He said: “A call will come. But a clear message is being sent.
“Netanyahu was Trump’s 3rd call. To quote Dorothy, we’re not in Kansas anymore.”
Many Democrats were angered by Mr Netanyahu’s close personal relationship with the former president.
Addressing Mr Trump in 2019, the Israeli leader said: “You’ve always been there, including today. And I thank you.”
Speaking to USA Today, Natan Sachs, a Middle Eastern policy expert at the Brookings Institute, explained the relationship’s appeal.
He explained: “Trump is far more popular in Israel than he is in the United States.
“The result is that anything that emphasizes Netanyahu’s relationship to the administration is a very good political prop for Netanyahu.”
