Yes you remove the force-contact variable from the <domain> tag and only set it in the individual <user> tag.
That is how you can pick and choose which ones do the options.

You can also configure a force-expires on each user so the register will reply with a very short expiry time to
trigger the client to re-register at any frequency you want. You can enable this without enabling the force-contact
The force-contact option automatically sets the expire time to 20 seconds but you can make it even lower if you wish.

I think so. And this why I think about to do it myself :-)
If someone other see it useful...

If I have success in doing such changes to sources, I'm very glad if you
help me with testing. Thanks Jonathan!

Yes, I agree. But few of them (for example Nokia mobile phones) can't do
that. And this why should I send keep-alive packets (dummy packets or
valid OPTIONS), but only to few of NATed UACs. Thus I have to have an
option to distinguish between UACs which need to be nat-pinged and which
not :-)
