Mrs Keneally told the inquiry Mr Obeid called her in mid-2010 to discuss a proposal by AWH for a public-private partnership with the state government.
The inquiry has heard the Obeids stood to make up to $60 million from the PPP.
Mrs Keneally said she could"count on one hand"the number of times she had spoken to Mr Obeid on the phone,and she turned to her husband when the phone rang and said"oh,for God's sakes".
Mrs Keneally said Mr Obeid did not deny that his youngest son,Eddie junior,worked for the company.
