Hello Attila,
yes I'm refering to userinfo and that also includes telephone-subscriber. But
as the paragraph from RFC3261 clearly states you can build the userinfo part
according to the rules from RFC2806, but you have to escape every character
which is not allowed in SIP. And as the "user" from the RFC3261 BNF does not
allow # as character you have to escape it in my opinion.
user = 1*( unreserved / escaped / user-unreserved )
unreserved = alphanum / mark
mark = "-" / "_" / "." / "!" / "~" / "*" / "'" / "(" / ")"
escaped = "%" HEXDIG HEXDIG
user-unreserved = "&" / "=" / "+" / "$" / "," / ";" / "?" / "/"
At least I do not see any # in these characters, so escaped seem the only
option to me.
Regards
Nils Ohlmeier
