From Aleksandr Shutko: SNAC(17,04) registration request SNAC(17,04) BUCP__REGISTER_REQUEST
|
Use this snac when you need new ICQ account (uin/password).
Server should reply with SNAC(17,05) containing
new uin. This snac mean that registration finished succesfully.
Server also can reply with SNAC(17,01) if it can't
create new user account.
