Subject: [SIP] Use of Record-Route and Contact Headers

Hi,

Table 4 of bis02 states that a Contact header can occur in the following
response types:

1xx
2xx
3xx
485 (Ambiguous)

However, Table 5 states that Record-Route can occur in the following
response types:

2xx
401 (Unauthorized)
484 (Address Incomplete)

I don't see how  a response can include a Record-Route, if it can't contain
a Contact.
I believe that 401 and 484 should be added to the list of response types for
a Contact header.

What do you think?

Cheers
Phil (Just appreciating how overloaded Contact header is! :)
