Lorenzo,
The reason 401 is used for the REGISTER message is because the proxy (which
is also the registrar) is acting as the UAS for the REGISTER transaction. If
the proxy did actually proxy the REGISTER request on to a registrar and the
proxy needed credentials, it could respond with 407.
Endpoints (UAs) of the transaction use 401, and intermediate proxies use
407.
cheers,

Can a Proxy respond with a 407 instead of 401 when I try to register on it.
I have always seen:
401 message in reply to REGISTER and 407 message in reply to an INVITE.
Thanks
Lorenzo
