You could put the callmanager behind the 3640 and do some kind of NAT to translate a public address to a private address for the call manager. The 827-4v would be a h.323 device in callmanager so make sure you are NATing the h.323 correctly. Where is your voice going to terminate to a pstn gateway or an IP phones? Where are these devices going to be in relation to the callmanager?
The 827-4v would connect to several pstn gateways besides the callmanager and the phones connected to that. The purpose is that the routers only talk with the 3640 and this proxies traffic to all other devices. What is the 'correct' way of nat'ing this?
And do the 827's register with the 3640 and/or the callmanager?
Unless you are using a gatekeeper the 824-4v should be pointed at teh callmanager. The routers do not support tandem switching voip calls. So if you point the 827-4v at the 3640 the call manager could not use it as a gateway. I think I might have misspoke when I said configure it correctly. But you do need 12.1(5)T as a minuim to have NAT support for h.323.

The short answer is that you don't.... That isn't entirely true while at
the same time it kind of is, but for the most part you don't configure
the softkeys. You enable or disable them via TCL. Here is the long
