I try to do static NAT to redirect SIP (udp 5060) from outside ASA interface to CCM 6 on the inside network. NAT works fine (redirect packet to CCM), but inside SIP packet address wasn't changed by ASA, so SIP didn't work. How can I fix this problem?
Hi! Yes, "inspection sip" is enabled (global settings). ASA 7.07 version. I think that inspection doesn't work in my case or ASA doesn't implement inspection for static NAT.
Can you try to do a static 1-to-1 translation and test if the SIP inspection is changing the IP address.
Also if you can post the debug sip and debug sip ha I can confirm you the problem.
