I'm currently 'using' dundi and it works great for small environments. I
guess that up to several tens of nodes and a few concurrent calls going
on, a set of * boxes clustered using dundi is quite an elegant solution.

Now, if you have hundreds or more clients all registering quite
frequently, you * boxes will have an hard time keeping up. In that case,
it makes lots of sense to set up a set of (Open)SER registrars to handle
that load and have * take on the role of a 'border' gateway, of course
still clustered to achieve maximum availability and an opportunity to
take one down for maintenance without impacting production too much.
Now, I haven't had time to test this, but from what I hear, this is the
way o go for larger environments. I haven't had time to experiment with
this, but it seems feasable.
