That's only possible with a proxy server. Asterisk is not a proxy
server. It acts as a user agent. So unless you implement a SIP proxy
server module for Asterisk, you wouldn't be able to do what you want.
I reckon that this would be quite a bit of work though.

However, the reinvite=local facility is something that would make a
lot of sense on LANs and which can be implemented with relatively
modest effort, since all you have to do is check if both phone's
addresses belong to the same subnet and then allow or disallow
reinvites acordingly. That's one particular test followed by one
particular action, pretty straightforward.
