The NetGen Smart ATA® HX422E is an ATA that not only offers the service provider a high-function voice-fax ATA with FXO capability, but also includes patented technology (US patent 9,094,419) that finally makes FoIP calls as reliable as PSTN fax calls. Although this unit has 4 telephone ports, only two of them, the FXS ports, are usable with fax machines.
Please upgrade your firmware to the newest version available. Current firmware version required is: Version 351. See the "Upgrade Guide" found in the firmware download package for each release from Netgen for the procedure for upgrading your ATA.
