Back in the olden days, I recall several modem vendors bundling PC fax software with their products. All of those old Win v3.1 apps created a fax file (eg, pdf or otherwise) that could be distributed via email.
Well, I don't remember any of them doing PDFs. PDF wasn't really around when Windows 3.1 was in its prime. And even those fax win-apps that were distributed with fax modems as recently as 2001 tended to write the fax images in TIFF or some proprietary format.
What are the equivalent low-overhead approaches (sort of T.37) today?
Any computer fax application that I know of will write the image to file, modern ones usually use TIFF. HylaFAX, mgetty+sendfax, efax, spandsp, etc. Then you just write the glue to make it deliver that fax image by e-mail. HylaFAX already has that built-in, and just requires some minor configuration to make it turn on. I don't know much about the delivery systems of the others.
I'd be very happy if I could simply connect an old analog 28.8 modem to the asterisk serial port, and drop a low-overhead app onto the system to address the fax stuff for today. Something very basic.
If you're happy to use the hardware and have a PSTN line availble to it, you're talking about HylaFAX. But I suppose that any fax package would work, with the exception of spandsp, which would require that you use an Asterisk-compatible FXO instead of that modem.
