Device and Users with DUNDi?

Hi,

I was looking at http://www.freepbx.org/v2/wiki/DundiClusterHack

Do you know if it’s possible to do this with user logons to devices? So If say 5 offices are connected via DUNDi you can login to any phone?

Thanks.

How can we get user_login agi to use or query Dundi if we set Dundi up?
