Hi, I'm reviewing my PIX 515E (7.04) configuration, in a VoIp environment(ipphone, CCM, gateway and ActiveDirectory are on 4 different subnet). I'm looking for a best pratice configuration... do you know where I can find it ? Does cisco recommand a certain security level for the CCM subnet ? What "fixup" they recommand to use ? What port they recommand to open?
