A470 should be R3.1 above, AMCC should be 4.2 above. You need AMC extension licences on your A470, then just use auto configuration.
Basically, the following are created in the PBX, AMC controller, users and the AMC terminals with the correct OTA profiles. On the AMCC, after the network settings are set, you need to turn on Auto-provisioning under Network and set your A470 IP address as the configuration server. All the configuration is pushed from the CS to the AMCC. Afterwards, you do client deployment to push config data to the redirect server. On the clients, download the configuration data and if all was correctly set, the clients will log on.
