>From and To header fields do not contain an IP address in most messages,
they typically contain a SIP URI with domain, something like
sip:jan at iptel.org. Comparing it to the IP from contact would be complex
since you would have to do a DNS query (which can return several IP
addreses).
There is no way of doing that so you will have to write a new module.
