Sending Faxes without a land line in late 2018??.............

If they are, I can't really tell from the datasheets.

Linksys' VoIP ATAs went to Cisco (hint: don't enable https - it's a desaster). Grandstream's ATAs run reliable and provide good performance. I'm able to get about 24kbps with a classic modem via G.711. Fax works also well if there isn't a grumpy fax machine at the other side. But this isn't anything new as we've seen this already back in the analog and ISDN days - some fax machines are picky. You can't go wrong with Audiocodes, but I think Grandstream can compete with them.

One tidbit regarding t.38 faxing directly build into printers...
I am a phone system admin at a medium sized company, and obviously also have to deal with faxing. Still, in 2020 :palm:
Most of our faxes are going out purely digital from a software fax. That is using a virtual CAPI Port that talks SIP with our Cisco Phone system, that then goes out via an ISDN PRI connection.
We also have some hardware faxes using Cisco ATA boxes 187, 189 or 191, connected to the phone system. Let me tell you, the now nearing 15 years in age ATA 187 still works best for this.
But on to printers. We have Canon Printers. And those also have the option to do T.38 over SIP directly. Of course this is a licensed option. But the kicker is, not only do you have to pay several 100 Euro for the license to fax over SIP, you *also* need the hardware fax module with the analog ports to actually do this :palm:
An ATA costs around 100 Euro, the license was around 400 Euro if i remember correctly with a similar amount for the hardware module, so even if finnicky, using that inbuilt option is just too expensive.

Had to fax the hospital to request records from them. Took ~1hr of trying multiple times, I'm guessing there is just the one fax machine on the other end.
But faxzero worked well, $1 for 10 page credits.
