A URI omitting any component with a default value will not

default value. For instance, a URI omitting the optional port
component will not match a URI explicitly declaring port 5060.
The same is true for the transport-parameter, ttl-parameter,
user-parameter, and method components.
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].
