The ATA will be a proprietary ATA that is serviced by the VOIP service provider. It works differently from conventional ATAs. I will plug the fax line into the ATA, and the ATA will plug into the wall’s outlet. The ATA will use a DECT radio for communications. The connection is 1.9Ghz, and that would be sufficient for sending and receiving faxes. The printer will still need to plug into a LAN port for network connectivity without having to use wifi.
