How does a Non-SIP Aware Firewall typically act regarding incoming traffic to port 5060?

A Non-SIP Aware Firewall is designed without specific rules or configurations to handle SIP (Session Initiation Protocol) traffic. As a result, its default behavior often includes blocking incoming traffic that it does not recognize or deem safe. Port 5060 is commonly used for SIP signaling, but since the firewall is not SIP aware, it does not have the intelligence necessary to discern legitimate SIP traffic from potentially harmful traffic.

In many scenarios, firewalls are configured to block unsolicited incoming traffic to safeguard the network from potential attacks. This default blocking behavior helps to prevent unwanted access and ensures a level of security for the network. Consequently, while a SIP-aware firewall would have special considerations for SIP packets and might allow them through based on pre-defined rules, a Non-SIP Aware Firewall typically errs on the side of caution and blocks such traffic by default.

Other choices do not accurately reflect the behavior of a Non-SIP Aware Firewall when it comes to incoming traffic on port 5060. For example, allowing all traffic would defeat the purpose of having a firewall, and redirecting traffic or restricting entry based on the day of the week are not standard operational behaviors for firewalls.
