Well, the originally quoted _sip_ URL
(sip:+1-800-123-4567;[EMAIL PROTECTED];user=phone) is clearly not
correct. Take a look at the BNF in section 2 of bis-03.
To be more specific, there are two problems with the above URL:
1. SIP URLs MUST have a hostname. In the URL quoted, +1-800-123-4567 takes
the place of hostname (not of user portion); however, hostnames cannot
contain "+" sign.
2. [EMAIL PROTECTED] represents a URL parameter. According to BNF, the
SIP URL parameter values are not allowed to have unescaped "@" signs in
them.
Thank you,
Igor Slepchin
