Asterisk doesn't care what audio you pass over those protocols. Your
problems will be due to packetization and transport adding delay to the
audio stream. You also will not be able to use any compression for this
type of call. So you take your risks and possibly will have to deal with
aborted faxes due to modem disconnections.

If you can, put the modem at the phone line termination and use
something like hylafax to move the images over IP.
