Posted by Dana Meltzer on May 22, 2018 12:07:36 PM

Is T.38 Fax Over IP (FoIP) causing you headaches? Are you experiencing surprisingly poor fax performance after converting/upgrading to SIP phone service? Can't find the source of your troubles? We feel your pain, we really really do. The good news is that FoIP doesn’t have to be a nightmare and in fact, when done correctly it can be just as reliable as faxing over traditional phone lines.


As you may already know all too well, there are many places a T.38 implementation can go wrong. It could be an issue with the underlying carrier, the equipment, a firewall, the fax software itself, or even the settings used during configuration. With so many moving parts the failures you're experiencing can seem unpredictable, .... random even. That’s where T38Fax’s experienced support engineers can help. Our motto is science, not superstition, and we're in the myth busting business.

Obihai OBi5vs Series Officially Certified

Posted by Dana Meltzer on Sep 3, 2015 11:32:30 AM

  At the core of our Power-T.38 service is a robust, reliable, standards-based and feature-rich T.38 Fax Over IP (FoIP) implementation that ensures a uniform and consistently high level of successful fax completion. We are fax industry veterans, and while other SIP providers might shrug and say “Oh well, it’s fax, what do you expect?”, we hold ourselves to exceptionally high standards when it comes to acceptable error rates. Naturally, we demand the same quality from partners who wish to have their technology certified for interoperation with our service.


We are pleased to announce that we have successfully completed interoperability testing with Obihai’s OBi5vs Series Universal VoIP Adapters. The OBi504 and OBi508 were each subjected to rigorous torture testing in our labs, and performed flawlessly. We found them to provide the stability, service, and reliability that our customers have come to expect.
