We're successfully communicating among VTA IP Phones and H.323 (Polycom) devices in our local IP address space. I'd like to call another Polycom device in another subnet. As I understand things, both the CallManager and the phone must be reachable from the H.323 device. Right now, the IP Phone is reachable, but the CallManager is not, and re-addressing the CallManager ain't gonna happen right away. Can I Static-NAT the CallManager(s) to place them in a subnet reachable by the remote H.323 device? Or is my basic understanding wrong?
The problem is not between the phones and CCM, it's between the remote H.323 device and CCM. It looks like I can use static NAT, but NAT has to be H.323 aware. I'm scrounging for a router that can legally and physically run such an image, and will test it later this week. Using the second NIC is an interesting idea, though. I'd have to modify the CCM route table and probably wind up with an unsupported configuration, but it'd be fun to try.
