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.

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?

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.

So far so good We have been using sFax for a number of months now. It's working well except we are having a bit of trouble porting existing numbers which seems to take up to 2 weeks.

thi ha could be bettet Why is it that when my company receives and sends faxes, I get three emails telling me each time? It didn't used to be this way, but my email notifications are tripled. I wish there was a way to call and talk with a representative rather then send an email each time I have a need or question. The lag time is just too slow sometimes to get done what I need to do.
