Thanks Olle, I do appreciate the warning..
If I rewrite the from-domain with uac_replace_from this works, but the
sip-standard forbids a proxy to do that if I recall correct?
We try to build a central point where our asterisk servers can get
incoming and send outgoing calls to without having to care about number
format, authentication and what gateway should we use.
The main reason of choosing kamailio was the factor of scalability as we
would like to be able to add more asterisk's behind this server over
time. Right now we have about 3 asterisk server communicating directly
with our teleco's. Any suggestion how we should build this are very
appreciated.

I've done some tests with the UAC module to
authenticate to a remote proxy. I've based my config on this example:
http://docs.huihoo.com/opensips/tutorials/uac/ar01s06.html (example 9)
But as I would like to use more than one remote proxy (=more than one provider) per
asterisk server this needs some more work.
Use the realm based authentication in
Asterisk. Trying to insert authentication into a dialog will propably cause issues (as
documented in the UAC module).
The other side seems to use the From: user domain as a realm. In Asterisk, you can set it
with the fromdomain= variable.
