RFC 3261/19
SIP follows the requirements and guidelines of RFC 2396 [5] when
defining the set of characters that must be escaped in a SIP URI, and
uses its ""%" HEX HEX" mechanism for escaping. From RFC 2396 [5]:
The set of characters actually reserved within any given URI
component is defined by that component. In general, a character
is reserved if the semantics of the URI changes if the character
is replaced with its escaped US-ASCII encoding [5]. Excluded US-
ASCII characters (RFC 2396 [5]), such as space and control
characters and characters used as URI delimiters, also MUST be
escaped. URIs MUST NOT contain unescaped space and control
characters.
