topic PIX & Call Manager in Network Security https://community.cisco.com/t5/network-security/pix-call-manager/m-p/244441#M593478 <P>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. </P> Fri, 21 Feb 2020 07:20:08 GMT peangvall 2020-02-21T07:20:08Z PIX & Call Manager https://community.cisco.com/t5/network-security/pix-call-manager/m-p/244441#M593478 <P>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?

Try using a 1 to 1 NAT or a static NAT for the phone.</P></BODY></HTML> Thu, 08 Apr 2004 12:13:07 GMT https://community.cisco.com/t5/network-security/pix-call-manager/m-p/244442#M593479 mathia5 2004-04-08T12:13:07Z
