Represents automated SIP reconnaissance activity characterized by multiple unauthenticated SIP methods (such as REGISTER and INVITE) issued using bot-like Call-ID formats. This behavior indicates an attempt to enumerate valid SIP users, extensions, or call routing behavior by systematically probing a SIP service without establishing legitimate registration or dialog context. The use of a numeric-only, hyphen-delimited Call-ID format across different SIP methods strongly suggests an automated scanner or fraud bot rather than a legitimate user agent.
