We've really got three classes of domains.
 1) local
 2) partner domains that we have some input into the control over
 3) other domains that we have a short dial code set up on; FWD.

I don't think that would then work in all cases, unless people like FWD have
radius that they'll let other people authenticate to?

But it is a possibility for the other cases.

It's as simple as that? So the SIP user agent doesn't have to communicate
via port 5060 with the gateway???

So it's unable to radius authentication for SIP?

Thanks for your help.
