asterisk users - Apr 2007 - Poor analog line quality, wireless "base station", FAX-ing

While pondering several issues, poor quality PSTN POTS lines, potential cost
savings with multiple cell numbers, the FAX problems over TDM400p, etc, I
wondered about:

Cell phone "Base stations" to replace POTS lines.  Devices to
"cradle" cell phones and connect to TDM400p, for instance, to mimic
PSTN.  Are there such beasts, how do they play with asterisk?

Will FAX work over such connectivity?

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.
