asterisk users - Aug 2005 - Control IAXy Provisioning from a central

If i were to use Asterisk with, say 1000 IAXy's, is there a way to
provision them from a central spot? It would be very improper to have
to let each end-user do this by him/herself...

The manual and documentation for the IAXy is very limited, and i can't
find anything about this kind of things... Anyone uses the IAXy in an
environment like this and can help me with some answers?

Thanks
Best Regards
