Can unsolicited UDP barrages be turned off?

"NAT pinhole" is the term?
My last three consumer routers didn't need port-forwarding. Nor this semi-pro one (Cradlepoint MBR900 - great, by the way).

So is it some of the D-Link and Netgear crap out there?

Sure is a mess 'o packets flying out.
Do all the VoIP providers have to do this? I don't recall seeing it with two others.

All providers have to do something if their customers are using consumer routers since virtually none of them handle NAT in a VoIP-friendly way.

Like I said one alternative is just an insanely short re-registration interval where the adapter is just constantly refreshing its registration.
