Then don't do any of those things. 1. Confirm your firewall at the remote end does not have an ALG or SPI turned on. 2. Confirm your firewall where sipx is installed is handling NAT via symmetric port nat.
Try and register a softphone FIRST. After your softphone registers properly, make sure you manually set the FTP address for the remote phone to the public IP of the sipxecs installation. This also means FTP must be NAT'ed to sipx from that firewall. Do not use above firmware 3.1.3RevC on 4.0.4.
