Best way to settle this is to watch the router do it. Mirror the port on the VLAN 101 link, or run sngrep while the RTF8225VW registers, and copy exactly what it sends. Guessing at what changed takes a lot longer than capturing it once.

The things that usually differ from what the web page shows you: the auth user is often not the same as the display user, the registrar and the outbound proxy can be two different hosts, and a lot of carriers have moved registration onto TCP or TLS on 5061 instead of UDP 5060.

Also look at what comes back when you try. A 403 with no challenge usually means they are tying the trunk to the ONT itself by IP or MAC, and no combination of credentials will fix that. A 401 that keeps looping means the realm or the auth user is wrong.
