Skinny (SCCP) originally used various ports depending on the end device it was interacting with (see http://www.cisco.com/c/en/us/support/docs/voice-unified-communications/unified-communications-manager-callmanager/43881-ccm-tcp-udp-ports.html .)
And, this is a "voice support" exam, in the sense that wireless and the wired infrastructure supports voice. It's best to know the ports.
