The exchange had the room laughing as Paine told "Casey from Hong Kong" to "Martin" was "in a press conference, can he call you back?"
Apparently, Casey wanted Martin to check his emails.
Social media quickly reacted to the hilarious exchange.
It was a tough press conference for Paine with hard questions about how Australia were going in the Test and their goals over the past 12 months.
While Paine was able to offer a lighthearted break to the sombre atmosphere of the conference, he continued to answer the question without skipping a beat.
"One of my goals, every time we play Test cricket for Australia we want to win and clearly we want to move up the rankings," he said.
"A lot of my goals were around the way we went about it and getting the trust and respect back from our fans."
Speaking on SEN after the day's play, Paine said it was a tough day but some days are like that.
"It's certainly difficult, they were batting superbly," Paine said.
"Rishabh Pant's extremely difficult to bowl to when he gets going.
"It wasn't our best day, that's for sure, it hasn't been our best couple of days to be fair with the ball, but you can't fault the guys' effort, they were trying as hard as they could, you just have those days sometimes."
Pant has been a verbal sparring partner with Paine over the Test matches, including his sledge asking about if he can babysit, which his wife Bonnie answered during the week with a hilarious photo.
