It was Saldanha who put the call through.
"If we played any involvement in her death, then we're very sorry for that," said Greig, who described how she found out about Saldana's apparent suicide.
"It's the worst phone call I've had in my life," she said, fighting tears.
"There's not a minute that goes by that we don't think about her family and what they must be going through, and the thought that we may have played a part in that is gut-wrenching," Greig said.
The pair have been taken off the air by their network, which has not said when they might return.
"I don't even want to think about going back on air, to be honest," Greig said.
"I'm still trying to make sense of it all," Christian said. "We're shattered. We're people, too."
Greig said she'd willingly face Saldanha's family if it would help bring them closure.
"If that's gonna make them feel better, then I'll do what I have to do," she said.
"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," Greig said. "I hope they're OK, I really do."
