This is incorrect -- all our dialin routers are MAX 4000s and TNTs. We do
not authenticate based on calling number, but both the called and calling
number are logged through the Radius accounting server. If you have ISDN
PRI, at least with BellSouth, you get the ANI/DNIS information for free (they
can't turn it off), but they will charge you for it if you specifically ask
for it.
