Australian lawyer Melinda Taylor and three colleagues from the International Criminal Court were arrested after meetings with war crimes suspect Saif al-Islam Gadhafi, son of late Libyan leader Moammar Gadhafi, in early June.
Taylor is alleged to have passed documents to Saif al-Islam from one of his supporters.
Australian Foreign Minister Bob Carr said Taylor was allowed to speak with family members by telephone. She said she was well-treated and offered no complaints about her accommodations in Zintan, Libya.
"We find it (the phone call) encouraging but it stops short of being the news we want, and the family wants, which is her release," Carr was quoted by The Australian newspaper as saying.
Taylor's fellow staff members were told they were free to go but are staying with the Australian lawyer on a voluntary basis.
Tripoli has called for the ICC to apologize. The ICC maintains its lawyers are protected by immunity but said it regretted the incident.
