Number wouldn't port. We couldn't port our existing fax number. We liked the software, but it wasn't worth the amount of work that would go into changing the fax number everywhere for a doctor's office, nor did we want to pay for two services so that we could forward our number.

Experience OK but not worth the price. The cost of the service seems too high.

Terrible They have no tech support. No one answers the phone or responds to emails. Unable to renew our account online so now my account is locked. They now have our fax numbers hostage. User interface is form the 90s. Stay Away from this company.

Excellent service. Reliable. Secure. I am not a heavy user of secure fax, however I am a critical user. I chose Sfax because it was the only one at the time which offered HIPAA security and also didn't require a big buy-in or monthly fee for occasional users. The security is still there but recent changes have made it less practical for occasional users like myself. If that does not apply because you are a business user, I can recommend Sfax without reservations.

Impossible to get any customer service. They never answer their emails or phone calls. I have tried to contact them 10+ times in the past 2 weeks and have sent numerous emails to support with no reply. No one has ever answered the phone and I'm always sent to voicemail. It frustrating trying to operate a medical office and not have our fax account work. This is something we use frequently and this issue needs to be handled right away but it's impossible to get any help.
