Hi Robert,
the new NAT traversal technique is intended to help with inbound calls
from clients that are behind a NAT and are not using H.460. So far we
only tested it in environments that only get inbound calls and don't
make any outbound calls, but it should work in all cases (except that
as before you won't be able to call out to users behind a NAT in mosts
cases). Please try it and report your results.
The GeoIP feature currently only works by country, because thats what
I needed. There is a similar database that would allow checking for
states and cities. Extending the code to use the other database is
probably not that difficult.
Regards,
Jan
