/* RFC 3261 19.1.4 URI Comparison.
* SIP and SIPS URIs are compared for equality according to the following rules:
* o A SIP and SIPS URI are never equivalent.
*
* o Comparison of the userinfo of SIP and SIPS URIs is case-
* sensitive. This includes userinfo containing passwords or
* formatted as telephone-subscribers. Comparison of all other
* components of the URI is case-insensitive unless explicitly
* defined otherwise.
*
* o The ordering of parameters and header fields is not significant
* in comparing SIP and SIPS URIs.
*
* o Characters other than those in the "reserved" set (see RFC 2396
* [5]) are equivalent to their ""%" HEX HEX" encoding.
*
* o An IP address that is the result of a DNS lookup of a host name
* does not match that host name.
*
* o For two URIs to be equal, the user, password, host, and port
* components must match.
*
* A URI omitting the user component will not match a URI that
* includes one. A URI omitting the password component will not
* match a URI that includes one.
*
* A URI omitting any component with a default value will not
* match a URI explicitly containing that component with its
* 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.
*
* o URI uri-parameter components are compared as follows:
* - Any uri-parameter appearing in both URIs must match.
*
* - A user, ttl, or method uri-parameter appearing in only one
* URI never matches, even if it contains the default value.
*
* - A URI that includes an maddr parameter will not match a URI
* that contains no maddr parameter.
*
* - All other uri-parameters appearing in only one URI are
* ignored when comparing the URIs.
*
* o URI header components are never ignored. Any present header
* component MUST be present in both URIs and match for the URIs
* to match.
