I couldn't behave myself and finally found the easiest way to find the port numbers quickly in the exam:
Just remember the question's wording... e..g. h323 sip mgcp skinny Jump on your flashy Cisco IOS and issue these commands rack02r1#show ip port-map | in mgcp Default mapping: mgcp udp port 2427 system defined rack02r1# rack02r1#show ip port-map | in h323 Default mapping: h323 tcp port 1720 system defined Default mapping: h323callsigalt tcp port 11720 system defined Default mapping: h323callsigalt udp port 11720 system defined rack02r1# rack02r1#show ip port-map | in sip Default mapping: sip-tls tcp port 5061 system defined Default mapping: sip-tls udp port 5061 system defined Default mapping: sip udp port 5060 system defined rack02r1# rack02r1# isn't that easy ? Why to remember if there is so many other things to remember? Cheers Frog
