If I take a 7960 and put it outside of a PIX and modify the cnf.xml file to point to the NAT'd IP of CM and open port 2000, should I be able to pass calls through the PIX? I can get it to register with the CM, but when I make calls, there is no voice. I have fixup for sccp and h323 turned on. ANy ideas? FYI, when I do a "show skinny" on the PIX, it shows the internal IP of the device I am calling.
