Is it legal "#" in a SIP URI???

In fact I don't allow it. I do this test in order to detect illegal 
characteres:

if ( $ru != $(ru{s.escape.common}) || ($rU && $rU != $(rU{s.escape.user})) ) {
 		sl_send_reply("403", "Forbidden, illegal characters in RURI");
 		exit;
}

And when a # is present in the URI the condition is not matched so the message 
is forbidden.

Anyway I've not verified if "#" is an illegal character according to some RFC.
