If you are considering buying a VoIP ATA, we recommend the new OBi ATAs. The OBi ATAs were built by the same engineers that built the PAP/SPA devices, and are sure to make an already great VoIP experience even better.
We do not recommend the new SPA112 and SPA122. Though the SPA112 and SPA122 are sold by Cisco as successors to the PAP2T and SPA2102, the new devices are not built on the same technology as the old devices and have received poor reception in the community.
Pianoguy is one of the biggest VoIP gurus on RFD (and in general):

Essentially, the engineering team that designed the PAP series left and eventually started designing Obihai ATAs.PianoGuy wrote:The PAP/SPA family of ATAs were an industry standard for many years until Linksys EOL'd them in 2012. Did you know that not only were Sipura and Obihai ATAs designed by the same engineers, those engineers also invented the ATA at Komodo technology 15+ years ago? OBi ATAs are really the latest versions of the PAP/SPA ATAs - granted, with more/better call routing features, better hardware, and better audio quality
