Yes.

An other thing to factor in, is how Asterisk's load could influence
its capability to let faxes passing through. To me, if Asterisk is
installed on a modern CPU (dual core and more) and is configured in
such a way that no transcoding happen, then passing faxes through is
easy and works reliably.

Opinions ?
