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.
