[Serusers] UA's under same NAT

You'd probably have to do some tricks to get that to work if your SER is
already set up for mediaproxy. 

By default, without mediaproxy and without NAT checks, this is exactly the way
things would occur because all your machines would register with their
internal IP and they'd just communicate directly with each other (as long as
the origin and destination of the call were in the same network). If you add
NAT checks to allow the UAs to speak to the outside world through a media
proxy, though, there's no real way for the ser server to know if the internal
IPs it's getting in its NAT checking are in the same subnet. 

You could probably set up some additional checks and add people in the same
subnet to identical groups and what not, bypassing the mediaproxy if the UA is
inviting a UA in the same group.

It'd be rather convoluted, but workable.
