Hylafax and iaxmodem

I just installed hylafax and iaxmodem. I am using voip.ms for my fax line and i can send faxes out just fine. When I try to receive them I get
Dec 31 21:33:08.02: [ 1333]: TRAINING failed
Dec 31 21:33:08.02: [ 1333]: <-- [9:AT+FRH=3\r]

Dec 31 21:33:09.74: [ 1333]: RSPREC error/got DCN (sender abort)

Are there any settings that I can change so I can receive faxes.
I get this from faxzero Your fax to xxxx at xxxxxxx has failed because the phone line was unexpectedly disconnected.

it is very strange that I can receive faxes when I use google voice.
