Represents an automated SIP INVITE request likely generated by a scanner or bot rather than a legitimate user agent. The behavior is inferred from a combination of a numeric-only SIP Call-ID format and a direct INVITE to a long numeric target without prior registration or dialog context. This pattern is commonly associated with SIP service probing, extension discovery, or early-stage toll-fraud reconnaissance. This behavior indicates reconnaissance activity against a SIP service but does not, by itself, confirm successful call setup or financial abuse.
