2 entries are registered on port 3002. It is a registered port (1024–49151) — IANA records an assignee, but nothing stops other software from listening here, which is why the number carries more than one entry.
Miralix CSTA is a port used primarily by Miralix solutions implementing the Computer Supported Telecommunications Application (CSTA) standard, which enables computer-telephony integration. It facilitates call control and telephony event monitoring between telephony hardware and software applications, commonly within call centers or unified communication environments.
The registry says what 3002 is registered to. What is listening on it right now is decided by the host, and only the host can be asked. Each of these prints the process behind the socket.
linux
ss -ltnp | grep ':3002\b'
macos
lsof -nP -iTCP:3002 -sTCP:LISTEN
windows
netstat -ano | findstr :3002
On Linux and Windows the process name comes back with the socket; on macOS lsof needs sudo to name a process that isn't yours. Match what it prints against the 2 entries above.
A port number is not a service. Anything may listen on 3002 — what you actually met is decided by the host, not the registry. If a service is missing here, it belongs in the registry.
