[Freeswitch-users] NAT-ed phone only got some incoming calls?

I have a customer with a natted Yealink T20P...

Current reg: http://pastebin.freeswitch.org/19290
Two call traces, FS log side: http://pastebin.freeswitch.org/19286

One rang, one didn't. The local information for the phones is the same --
so NAT seems to be handled properly. Is this an issue with the remote
router dropping packets or something...?
I see 4 inbound calls to that device today, and 1 of them doesn't have a
progress stamp so I assume that's the same as above -- it never got a 180

I think I can dig up the actual sip traces, if that matters, but it's not
in the most convenient of formats.

Some illumination would be appreciated.
