Yes, it is possible to push peer information as well as pull it. You could also, as you say, limit the number of registration servers (i.e. servers doing both the registration and DUNDi) and then only query to them. I'm sure the hybrid model you suggest would work as well although it'd need testing to see whether you got more performance out of splitting the DUNDI and registration roles or just adding more dual-purpose machines.

Lets say you have a cluster of, say, 10 Asterisk servers. After doing a local lookup to see if a number is available locally, in order to find out if the number is available on one of the other 9 servers, this peer has to query all 9 remaining peers.
Is that true?

Is there a way to have 'registration servers' that accept registrations from phones, and which somehow notify 'DUNDI servers' (two for redundancy) that the registration servers query? To terminate a call, a peer would only have to query the DUNDi servers, not every other peer. After looking at the config files, I can't imagine how this could work, or if it's even possible with DUNDi.
