It is being reported that the deadline, which expired on July 2 (Sunday), has been extended for 48 hours on the request of Kuwait mediating in the crisis.
The energy-rich Gulf state was given an extra 48 hours to respond to a list of 13 demands such as closing down state-owned al Jazeera and cutting off alleged links to Isis, Iran and the Muslim Brotherhood which the Doha government had previously described as so far-reaching they appear meant to be rejected.
They accuse it of supporting "terrorists" and of being too close to Iran, Saudi Arabia's regional rival.
Saudi Arabia, UAE, Bahrain and Egypt have 13 demands in front of Doha.
The response will be the focus of a meeting in Cairo on Wednesday of foreign ministers from the four countries that have cut ties with Qatar. "Qatar is prepared to face whatever consequences, but as, I have mentioned ... there is an worldwide law that should not be violated and there is a border that should not be crossed".
On 20 June, the US State Department says it is "mystified" that Saudi Arabia has yet to produce a clear list of demands.
Trump, spoke to Saudi Arabia's King Salman bin Abdulaziz, as well as Abu Dhabi's crown prince Sheikh Mohammed bin Zayed al Nahyan, and Qatar's Emir Sheikh Tamim Bin Hamad al Thani.
"President Trump, nevertheless, believes that the overriding objective of his initiative is the cessation of funding for terrorism", the White House readout said. The decision though does not seem to make any change in pacifying the present crisis as Qatar is set to reject the thirteen point ultimatum.
Doha had been asked to shut leading news channel Al Jazeera, sever relations with Iran, stop the establishment of a military base by Turkey in Qatar and cutting military cooperation with the North Atlantic Treaty Organisation member.
Qatar denies it funds militants and justifies its ties to Iran due to the countries sharing a large offshore natural gas field.
The U.S., which has 10,000 troops stationed in Qatar in its main Middle East base, has sought to end the crisis with U.S. Secretary of State Rex Tillerson urging for a dialogue between the two sides.
