Encoding SIPURI parts #2
Description
The SIPURI encoding does not match with the URL encoding.
It would be a great addition having a proper escaping function.
The url.PathEscape and url.QueryEscape are a great resource.
More information on that pls read - 19.1.2 Character Escaping Requirements(https://tools.ietf.org/html/rfc3261#section-19.1.2)
