Fax software – for high volume of receiving faxes.

Hi friends,
I would like to know different fax softwares that are good to receive large volume of faxes and sorting to concern folder based on senders information ie., there will be a folder for each sender. What I want is, the received faxes should go to the cocern folders created based on senders informaton (may be from coversheet)and the fax software should be good for receiving lare number of faxes (2000 per day approx.)
Thanks in advance.
