After changed from Spa122 to obi200, everything seems good except that I found out I can not fax through freephoneline( faxing machine is Samsung scx3405FW 4 in 1) anymore. But I can fax through Google voice (obi200-Goolge voice-Samsung combination), and other people use (obi200-freephoneline-brother faxing machine) combination seems also OK with fax. ???
Yesterday I upgraded to the newest firmware and I try 3 fax out and 2 fax in and they all went through successfully and easily! Thank you OBI engineer for your handwork!! Now the Obi200 is perfect for me! ;D
