I remember reading the same kb article when investigating how to set my Vonage
bandwidth to the low setting which I was never able to accomplish.  I suspect
the prefix was to manually switch the codec used to the higher bitrate but since
my connection has always been stuck at the highest bitrate I never needed to
adjust it for fax.

I have never needed to open any inbound ports or setup inbound NAT.  I suspect
this depends on the ATA as the one I have which is just a couple months old
apparently maintains an outbound connection at all times.
