Darijo,

I have never tested this, but theoritcally this should be no problem. You will need to make sure that the PIX has ACLs for the IPMA ports along with the phone signaling and media(which the PIX already has a fixup for).

Here is the link to the CCM TCP/IP port usage. All of the IPMA console ports and http from the phones will need to be allowed.
