Your right using dialplan extensions for every server is not scaleable and
will be a nightmare to manage.

Yes the 20+ servers are remote servers connected to each other by fiber
optic. I know passing rtp directly between phones will be bad for bandwidth
as I cant use trunking. But then can I really have every machine in say a 50
machine asetrisk cluster have an IAX connection to every other.

Cant I do some sort of on the fly IAX connections (trunks)

you are absolutely right.

I dont have IPsec or anything for now (btw cant the IAX trunk be encrypted)

My main issue is how do I connect say 50 remote asterisk servers to each
other and make it easy to add more servers in future.
