Technical Details

what runs on :3097

This is an SCTP service for transporting Bearer Independent Call Control (BICC) signaling, as identified by ITU-T Q.1902.1/Q.2150.3. SCTP establishes an association between signaling peers and carries messages with message boundaries; the SCTP handshake uses INIT, INIT ACK, COOKIE ECHO, and COOKIE ACK chunks. The assignment is for carrier telephony signaling and is not a TCP service. SCTP does not encrypt this traffic by default.

security overview

BICC signaling can influence call setup and related telecom operations, so an exposed listener should be reachable only by authorized signaling peers on a controlled network. Unauthorized traffic could cause signaling disruption or service/resource abuse; SCTP does not provide encryption by default. This is a niche assignment with no open instances reported in the supplied scan data, and no specific known vulnerability is asserted here.
