Poor quality POTS lines and fax problems do seem to be related. The
added latency and potential of jitter and dropped frames doesn't do
too much to help.

I've never had any luck with FXO with analog lines, much less with
anything that wasn't a real PSTN line, problems with hangup detection
and such.

No but if you only wish to fax you can connect a data cable and send
it AT commands to transmit a fax.
