Not as effective receiving faxes as a traditional machine. We are unable to receive all faxes. 5% of income faxes are never received and we have to direct people to fax to our back office fax line Update: I have tried multiple times to have this issue resolved through support. I am told the person sending the fax has a problem with their phone line. but yet they can fax to my back office fax no problem. Tell me how that makes sense?

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.

Nonexistant support, incompetent staff Our experience with Sfax has been nothing but frustrating. E-mails to support on simple issues go unanswered. We tried to port our numbers over, but after 4 months the porting department seems to be unable to enter a port request properly even after being provided with a CSR from our current carrier. When we checked with our current carrier's port-out department, it looks like only half of the port requests are making it to them. We ported our voice numbers to a different vendor just before attempting to port our fax numbers and everything went fine. I'd recommend avoiding sfax or any j2 brand.

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.
