Appendix 12 – Characters allowed in SIP URIs
The following character set is allowed in SIP URIs (further details may be found in RFC 3261):
a-z / A-Z / 0-9 / "-" / "_" / "." / "!" / "~" / "*" / "'"/ "(" / ")" "&" /
"=" / "+" / "$" / "," / ";" / "?" / "/"
"=" / "+" / "$" / "," / ";" / "?" / "/"
If other characters are needed they must be ‘escaped’ using "%" HexDigit HexDigit
where HexDigit HexDigit is the ASCII value for the required character.
For example, firstname%20lastname@company.com - %20 is the space character.
