Hi Richard,
Changing UA is not always a viable solution due to pricing and other technical issues. Every UA has something broken in its implementation and it would be very costly to change it because one thing (in this case, NAT) is broken.
I think trying a workaround in a router is more difficult that trying in a UA. The best thing should be working with a non broken UA as this can avoid broken routers like the pne you are talking about.
In your case, another working solution is reduce the REGISTER expire time. If you configure an expire of 60 seconds, your UA will generate traffic from the interal side of the router which will keep the binding.
If you want a router with NAT ping, means that the router must work in ALG mode which is a very bad thing. Most ALG routers i know are totally broken about SIP.
