Yes, the character '#' may not appear in a SIP "user". This is inconvenient, because '#' is one of the DTMF characters. However, '#' can be *represented* by %23 in a SIP "user", and this is what is done when a UA wishes to send a "user" that the human user thinks of as "I dialed #." E.g.:
INVITE sip:6300%[email protected] SIP/2.0 ... Of course, there is no rule requiring a user agent to provide the human user with a method to cause such an INVITE to be sent. But SIP elements are required to be able to *receive* and correctly process such an INVITE. Well-mode SIP phones do all this correctly.
