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.

Hope this helps,

Actually I believe that no inspect command is needed for SIP.

Current IOS applye "NAT SIP ALG" automatically without configuring anything.
