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!

And I have nearly no experiences with FreeSWITCH :-)

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 :-)

Best regards,
