I can;t speak about the T400 as I use and X100 but I have made a fax call
over it and indeed received one. I also have sent faxes over iconnecthere
and galaxyvoice with success using ulaw. My fax uses a Sipura interface.

To receive faxes I got one of those washington state numbers. Seems it can
be bludgeoned into ulaw too.
