I would like to permit a softphone on my laptop to connect to my astlinux
box from anywhere in the world. This would mean keeping port 5060 open,
which is a potential security risk? Is there a way to restrict access by
mac address? so that my softphone on *my* laptop can connect, but no one
else's can (even if they know the extension/password.
Thanks.
