Those who say that FAXing is hit-or-miss are correct. Much depends upon the broadband service. When I had Comcast with 6 MB speed, FAXing was usually successful. Now that I live where extended DSL at 512k is the fastest available, it's usually not successful. Voipo's outgoing FAX feature isn't reliable, either. About 50% of the FAXes which I send via Voipo are not successful. There are about 6 free FAX providers which permit sending 2 FAXes per day. I use one of these for the few that I send, and use a free e-fax account for inbound FAXes. It doesn't appear that e-fax offers free accounts any more, so try K7.com.
