From and To header fields do not contain an IP address in most messages,

Hi, I need to make a decision and/or set a flag in the routing script based on the IP address of the address record for the contact. Basically, I need to check if the current IP address of the From and To in an INVITE are the same and act accordingly. How do I do this? Do I have to write an exec module and/or a custom ser module? I guess the latter is the way to go, unless there's a better way, as I don't want to span a new process (exec) for each "INVITE" that passes trough the router. Any hints are greatly appreciated.
