Re: NAT Support?
I disagree.
My previous job was at a SIP-based VoIP provider. We had SIP softphones on the computer as well as hardware phones.
I would say that about 99% of the time they worked just fine behind NAT w/out any configuration being done on the router.

Your NAT gateway was probably SIP enabled. They need a SIP ALG code to do that (Application Level Gateway) or your VOIP softphones/hardphones implemented STUN extensions for VOIP.

We found it to work on plenty of old routers, etc.
