Hi,
ou have to list them before tcp or udp keywords, otherwise their control streams will not be inspected and there will be no provision for data sessions.
ip inspect name Internet
ip inspect name Internet h.323 router-traffic
ip inspect name Internet sip router-traffic
interface FastEthernet0/0
ip inspect Internet out
Below is the link for more reference.
