Which ports are commonly associated with SIP (Session Initiation Protocol)?

TCP/3389 and TCP/5060
TCP/5060 and TCP/5061
TCP/389 and UDP/514
UDP/162 and TCP/445

The correct answer is: TCP/5060 and TCP/5061

SIP, or Session Initiation Protocol, is primarily used for initiating, maintaining, and terminating real-time sessions that involve video, voice, and messaging applications. The correct ports associated with SIP are TCP/5060 and TCP/5061. Port 5060 is the default port used for SIP communications, allowing SIP messages to be sent and received over a TCP connection. This port is used not just for the SIP itself but is also utilized for SIP signaling in most implementations. Port 5061 serves the same purpose but specifically uses Transport Layer Security (TLS) to provide a secure connection for SIP signaling. This makes it advantageous in environments requiring encrypted communications, such as VoIP implementations, to protect sensitive session information from potential eavesdropping or interception. The other port options provided do not relate to SIP. For example, TCP/3389 is associated with Remote Desktop Protocol (RDP), TCP/389 is used for LDAP (Lightweight Directory Access Protocol), and UDP/162 is used for SNMP (Simple Network Management Protocol) traps, while TCP/445 is used for SMB (Server Message Block) protocols. These associations make it clear that the correct answer aligns with the known ports for SIP, reinforcing your understanding of network
