I already explained that # is not allowed in a SIP URI (also in the SIP Request URI, of course).
On the other side, the answer is "Yes, of course, provided that your SIP equipment follows the standard and encodes the # character. You are allowed to dial that character, but any SIP-compliant device (useragent) is not allowed to transfer it verbatim in a SIP uri, but has to encode it - much like many international characters in a HTTP uri.
Yeah, but in Kamailio you must decode it using some "undecode" transformation. Kamailio itself doesn't undecode it by default and treats %23 hexedecimal code as 3 normal ASCII chars: '%', '2', '3'.
By some reason, the '#' is used a lot in telecom/mobile operators dialed extensions (e.g., charging credit on mobile phone), not sure why is not allowed in SIP.
That is the reason kamailio (openser) does accept '#' in the username. If you want to be strict compliant to SIP-RFC then you have to use the transformations. Not sure what would be the best to make default for the future ....
