I'm not claiming to be an expert on the matter but I'm running here in 
my small office 2 softphones and 3 hardphones (I'll replace the 
softphones soon as well) and all of them are being NAT. The asterisk is 
located remotely and all the clients connect to it with the help of 
public STUN servers. My softphones are X-Lite and my hardphones are 
Snom. I also worked with Grandstream ATA (Handytone 286), Motorola ATA 
and Welltech phone - they all worked just fine.
