sorry but can you then explain this paragraph from RFC3261 to me: The BNF for telephone-subscriber can be found in RFC 2806 [9]. Note, however, that any characters allowed there that are not allowed in the user part of the SIP URI MUST be escaped. I think this says that even if it is allowed to use # in telephone-subscriber part, you have to escape it if you are going to use it in a SIP message, because # is not allow in a SIP message at that place. If I'm wrong then please explain to me why and how do you interpret the above paragraph.
