Summary:                    Some characters (such as #) are not escaped in SIP
headers
Description: 
Had a conversation with OEJ yesterday about the '#' character not getting
converted in all areas of the SIP headers to a %23. Here are some comments
from our conversation:

RFC 2396 says:

"The character "#" is excluded because it is used to delimit a URI from a
fragment identifier in URI references (Section 4)."

The SIP RFC says:

"Excluded US-ASCII characters (RFC 2396 [5]), such as space and control
characters and characters used as URI delimiters, also MUST be escaped."

The Mediatrix device is at least one of them. Also, the Nortel PBX doesn't
work either.
