[asterisk-users] asterisk across a firewall

[Erick Perez]

Excuse my ignorance but if i have an asterisk in a LAN, and i have
users in their homes/internet (dozens), in order to correctly connect
those users across my firewall, what is the technology that i need to
buy, called?
secure border gateway?
session controller?
secure gateway?
the audiocodes site seems to have many names for the same thing...but
i better ask here and learn before i make a big mistake.

my customer has a dumb firewall (not SIP aware) that will not replace.
he wants another box to do the magic.
