Which port is commonly used for SIP signaling without TLS?

Explanation:
SIP signaling without TLS uses the default port 5060 with UDP. This port is defined for non-encrypted SIP signaling, making it the most common and widely deployed configuration when encryption isn’t involved. TLS changes the port to 5061, so that’s for encrypted signaling. While SIP can operate over TCP as well, the standard pairing for unencrypted signaling is UDP on 5060. The other option on a different port or with TLS isn’t the typical setup for non-encrypted SIP signaling.
