Mel Greig and Michael Christian have both apologised for their actions, saying they were devastated by the apparent suicide of London nurse Jacintha Saldanha.
The mother of two was found dead on Friday after answering a call from the pair on Tuesday.
Greig and Christian, whose 2Day FM radio show has been cancelled, gave interviews to Channel Nine and the Seven Network in which they appeared shaken and contrite.
Sources say they were too distraught to speak to Channel Ten's The Project.

Grieg, who pretended to be the Queen inquiring on the condition of the Duchess of Cambridge during the call, told Seven's Today Tonight program she was haunted by the news of Ms Saldanha's death.
"Unfortunately I remember that moment very well because I haven't stopped thinking about it since it happened," she said through tears.
"I remember my first question was 'was she a mother?'."
She told Nine's A Current Affair she was thinking of the nurse's family.
"I've thought about this a million times in my head that I've wanted to just reach out to them and just give them a big hug and say sorry, and I hope they're OK, I really do," she said.
Christian said he hoped Ms Saldanha's family were getting "the love, the support, the care that they need".
Greig said she was the one who conceived the prank.
"We couldn't believe that it had worked. We thought a hundred people before us would've tried the same thing," she told Today Tonight.
"We just wanted to be hung up on. We wanted to be hung up on with our silly voices and wanted a 20 second segment to air of us doing stupid voices."
Greig told Channel Nine that nobody expressed doubts about the call going to air afterwards.
"We didn't have that discussion, we just did the process of what we do. We just handed it on to them and they have the discussion," she said.
"There's a whole team of people that work with us. We just go on and keep recording stuff or doing other prep.
"We do that and leave it for everybody else to deal with."
Veteran presenter Tracy Grimshaw, who defended the pair on Twitter at the weekend, told Fairfax radio they were "shattered people".
"They are under pressure that would break an old warhorse, and neither of them are old warhorses," she said.
Grimshaw earlier tweeted that her network did not pay the pair for the interview.
"Let me say clearly that our interview with 2Day FM hosts for tonight's A Current Affair was NOT paid for. Neither asked nor offered," she tweeted.
The ABC also sought interviews but was told the DJs were only talking to commercial TV to try and please commercial media partners.
A day ago their management was saying the pair would not be making any comment, but on Monday morning Greig and Christian were both made available for all three commercial TV networks.
Prank call ban
On Monday morning, Southern Cross Austereo (SCA), which owns 2Day FM, again defended the under-fire duo.
It said Greig and Christian followed proper procedures and the station tried to contact the nurses at least five times before the segment went to air.
The statement does not say whether the broadcaster received any response.
But a hospital spokesman said: "Following the hoax call, the station did not talk to anyone in hospital senior management or anyone at the company that handles our media inquiries."
SCA released a statement on Monday afternoon saying it has imposed a company-wide suspension of prank calls.
The company also said it was cancelling Greig and Christian's Hot 30 show, reiterating the pair would not be returning to the air "until further notice".
Greig told Today Tonight that neither she nor Christian were thinking about the careers.
"I don't want to think about that right now. There's bigger, more pressing issues and that's making sure that family gets through this tough time," she said.
"Our careers aren't important at the moment."
Chief executive Rhys Holleran said the company had initiated a "detailed and rigorous review" of its policies and procedures.
"As a leading commercial radio broadcaster, we must ensure that our internal processes and protocols are robust. We don't claim to be perfect and we always strive to do better," he said in the statement.
Communications Minister Stephen Conroy says the Australian Communications and Media Authority (ACMA) is considering fast-tracking its complaints process in relation to the matter.
