I don't know how you came to that conclusion. By "ignored", it means that
this component is not included in the matching operation.
Anyway, the URLs:
sip:foo.com
sip:[EMAIL PROTECTED]
are NOT equal. The reason is that the user portion of the SIP URL is NOT a
url-parameter.
Look carefully at the text:
user or telephone-subscriber, password, host, port and any url-parameter
parameters of the URI
must match. If a component is omitted, it matches based on its default
value. (For example, otherwise
equivalent URLs without a port specification and with port 5060 match.)
Components not found in
both URLs being compared, for which there is no default value, are ignored.
notice the text "and any url-parameter parameters of the URI must match".
So, we are talking here about things which are part of the url-parameter
BNF, which are delineated with semi-colon. This does NOT include the
username, port, password, or domain.
Perhaps people are confused by the term "component", which I will change to
"url parameter".
