I don't really get what you want to do. What connects to what, and which
IP address are we talking about (does the phone get an address from the
firewall? The firewall from the ISP?)? From which traffic should the IP
be extracted? Are you aware that this is almost certainly not very
secure?
In particular, if at least one side is unlikely to change IP, that
suggests a better solution...
