Hello everyone!
Please I need your support with a configuration about traffic SIP NAT-PAT on my Cisco ASA 5520, we have this configuration in this moment but no working properly.
In the global-policies, I tried enable and disable the SIP inspection without look any change.
This my topology:
Server----->Switch Core-----> FW ASA<----- Internet-----ISP SIP.
Someone had this problem?
