The phones do not require any special firmware. Therefore, they should first be installed as normal internal extensions, during which they will load the firmware provided by the IP Office system.

Once this process has been completed, the address settings of the phone should be cleared and the call server address set to the public address to be used by remote H.323 extensions.

It is assumed that at the remote location, the phone will obtain other address information by DHCP from the user's router. If that is not the case, the other address setting for the phone will need to be statically administered to match addresses suitable for the user's home network.
