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.
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.
