He has previously stated he would be keen to stay with Hertha, but wants the club to make a swift decision as he says other clubs are showing an interest.
"I want to have a decision by the end of March at the latest," Voronin told Bild.
"There are plenty of offers from other clubs and, if it takes too long to talk with Hertha, I will be heading into talks with other clubs.
"Every player needs faith, at Hertha I feel that the players and manager are putting trust in me."
He added: "I could not care less about the idea that Liverpool know what I am doing for Hertha. I am scoring goals for Hertha, not for them.
"I really do not give a damn about the way they are thinking about me."
Hertha's general manager Dieter Hoeness confirmed the club are hoping to agree a deal which will see Voronin stay at the club.
Hoeness said: "Andriy is in brilliant form actually, we really want to keep him at our club.
"I am hopeful we will be able to find a solution. It's a natural fact that he is getting more and more of the spotlight from bigger clubs with more money, and time really is a factor.
"We will do everything we can, but we will not rush into any financial risks."
