Former tabloid reporter Dan Evans said that a Sienna Miller voicemail message was played in the News of the World office and ex-editor Andy Coulson was among those who heard it, a jury heard.
He claimed that after picking up a message from the Hollywood actress' voicemail, it was "all hands to the pump" to get the story of an alleged Miller/Law/Craig love triangle, the court heard.
Timothy Langdale QC, the defence lawyer for Coulson, claimed that his client could not have heard the tape because he was not at work or even in London that day.
Evans insisted that Coulson definitely heard the tape but added that maybe his recollection of which day this was on was "flawed."
He told the court: "These events happened a long time ago and there are salient things in my mind about what I did. I am not here to make things up like I listened to Daniel Craig's voicemail. Why would I bother?
"This is not a fun experience for me. I had the guy's phone. I taped a message."
