From the RFCs:

Defining sip:user@host to not be equivalent to
            sip:user@host:5060 is a change from RFC 2543.  When deriving
            addresses from URIs, equivalent addresses are expected from
            equivalent URIs.  The URI sip:user@host:5060 will always
            resolve to port 5060.  The URI sip:user@host may resolve to
            other ports through the DNS SRV mechanisms detailed in [4].

Hope it helps.
