I'm sure that it will depend on how long the WinXP (or
whatever) connection sharing keeps the port 5060 mapping open.

I notice that Packet8 has the SIP box REGISTER every 30
seconds.  That's very often, but on asking they said it was
"necessary" to keep the port 5060 mapping alive on NAT routers.

So I guess if you or I were to setup the ATA186 to register often like
that, inbound calls will work too.

I'll do some experiments when I'm back home.
