Turkey claims to have shared records related to the murder of journalist and writer Jamal Khashoggi with the United States, the United Kingdom, the Saudis and others.
Turkish President Recep Tayyip Erdogan repeated his statement that Saudi Arabia knew who had killed Khashoggi.
Khashoggi, a critic of the Saudi rulers, was killed inside the Saudi consulate in Istanbul on 2 October.
Saudi Arabia admitted that he was murdered there, but denied that his royal family was involved.
Initially he had claimed that the writer had left the consulate unharmed.
The Saudis also denied comments allegedly made by Saudi hereditary prince Mohammed bin Salman describing Khashoggi as a dangerous Islamist.
The phone call to the White House came before Saudi Arabia had admitted that Khashoggi had been killed.
What do we know about murder?
There is still no consensus on how Khashoggi is dead. He entered the consulate to arrange the documents for his marriage.
Initially, the Turkish media had cited sources that Turkey had audio recordings that proved that Khashoggi had been tortured before being murdered.
Last week, however, Turkey claimed to have been strangled shortly after entering the consulate and its body dismembered "in accordance with plans made in advance".
No body was found and a Turkish official said he was dissolved.
Saudi Arabia has changed its account of what happened to Khashoggi.
When he disappeared for the first time, he said that Khashoggi had come out of the building alive. He later admitted that he was murdered, claiming that the murder was premeditated and the result of a "rogue operation".
He has arrested 18 suspects who, they say, will be tried in Saudi Arabia. Turkey wants to extradite the suspects.
Turkey has not publicly accused Saudi Arabia of murder.
"We gave the recordings, we gave them to Saudi Arabia, we gave them to Washington, to the Germans, to the French, to the British," President Erdogan said in a televised speech on Saturday.
"They listened to the conversations that took place here, they know it," he said.
No other country has admitted to having listened to the registration.
Khashoggi's girlfriend Hatice Cengiz called on world leaders to "bring the guilty to justice".
Who was Jamal Khashoggi?
For decades, he was close to the Saudi royal family and also served as a government advisor.

But he fell into disgrace and went into self-imposed exile in the United States last year. From there, he wrote a monthly column in the Washington Post in which he criticized the policies of the Crown Prince.
During a phone call with President Donald Trump's son-in-law, Jared Kushner and national security advisor John Bolton, Prince Mohammed said that Khashoggi had been a member of the Muslim Brotherhood, an Islamist transnational organization, according to the Washington Post .
It is said that the phone call took place on October 9, a week after Khashoggi's disappearance.
Reportedly, Prince Mohammed called on the White House to preserve the US-Saudi Arabia alliance.
In a statement to the paper, Khashoggi's family denied that he was a member of the Muslim Brotherhood and said that the murdered writer has repeatedly denied him in recent years.
What do the other countries say?
Saudi Arabia has faced a backlash for death, even by its allies, who have asked for answers.
US President Donald Trump said he was not "satisfied" with the Saudi account. However, he also said he was not willing to sacrifice lucrative arms deals with the country.
France has stated that it will impose sanctions, but will not provide details.
The British Foreign Minister Jeremy Hunt said that the killing of Khashoggi "probably" gave the United States and the United Kingdom the opportunity to exert new pressure on Saudi Arabia on other issues.
