Hi,
Seeing the firmware version in the User Agent header this phone is probably build on the same platform as the 79XX series phones and having the same sip-stack.
From experience I can tell you that sip-stack is really really horrible. I don’t know if you have bought a lot of these phone or just testing one.
If you’re just testing one you’re better of with the Cisco SPA500 series phones instead of these ones. Especially if you’re new to ip telephony, these phones will give you bad headaches.

This is incomplete. The normal flow is
-> REGISTER
<- 401
-> REGISTER
<- 200 or 403
If you look at the CSeq in the 403 you'll see its a reply to the register after the initial REGISTER.
401 contains a challenge that's used to generate the auth data to put in the 2nd register - that allows digest authentication which avoids sending the password in plaintext and uses a nonce to prevent replay attacks (an attacker can't capture the register and resend it later to auth themselves).
The digest includes the domain, if the user and password match perhaps the problem lies there...
