As for point 1 - what is there to try. A fax is not a modem. There is no
known (even in theory) attack against a fax to gain access.

Subject: Re: Vulnerability testing in analog modem
I had a similar pen test, it was on a xerox docucentra, I had several
concerns with the multifunction printer
1. there was/is no auditing of the fax connection, so I could try and
try and no one would never know about the attack.
2. the printer also had a web server, so I copied some test file to the
hd and set up my very own web site.
i believe it is possible to break out of the modem connection, via some
type of diagnotic route and get access to the network.
I recommend that to my client that they configure the phone jack for
outgoing calls only., turn off the web server, set passwords, etc.
I would be interested in hearing anyones thoughts about this. I have a
test coming up for a client on a multi function printer

I don't know about connecting through the fax to the network but there
is
another security concern to think about.
Fax machines, and printers, that have an internal HD for document
storage can be
a security concern. When the machine is sent out for servicing or
retired there
may be retrievable document images with confidential information on
them.
