Why would you want to do that?  Defeats the purpose of *having* the
DUNDi protocol.  Why not just program the extensions in at regular

In his configuration, when a registration server gets a request for the location of a phone, it queries the DUNDi Lookup server, which in turn queries the other registration servers on it's behalf. It doesn't actually cache the registrations itself.
