Which port and protocol is commonly associated with SIP signaling?

Explanation:
SIP signaling has a standard default pairing: port 5060 with UDP. This combination is the most widely used for non-secure SIP signaling because UDP is lightweight and well-suited for the quick, request‑response messages signaling needs. While SIP can run over TCP on port 5060 or use TLS on port 5061 for secure signaling, the 5060/UDP setup is the one most commonly associated with SIP signaling in typical deployments. The other options represent valid configurations in some environments, but they’re not the default pairing you’d expect to see most often.
