As I know the IP Phone to IP Phone is RTP and the port number is randam and the range is very large(16384 -32767 /UDP)
How to configue ASA/PIX to make the voice stream through firewall but not configre allow so large range port number?

Hi,
the PIX supports both SCCP and SIP "inspection" so in most situations will dynamically open the ports as necessary. Do you have CCM "inside" the PIX and you want to connect a phone "outside" ?

No, it's multi-sites configuration.
Each sit has it's own callmanager and have firewall between them.
The call setup is through H.323 singnal, I think it can use "inspection" fixup function. But how about the voice straem between two sites' IP phone? should I opne all udp port range or any special configuration I can do?
