But my ATA (= hard phone?) is *upstream* of the routers (for a reason)
which may be the crucial difference. If I moved the ATA downstream, I
would expect the problem to go away, but I haven't tried this so far.

Otherwise my setup is just the same. Different proxy , but that should
not matter.

Unless we are talking of a different message, turning off proxying will
eliminate the message :-)

So does mine, and yes all my different ekigas have different non
overlapping port settings which are distinct from those of the ATA.

You have missed the point, It's not the  ports: it's bandwidth. I have
256Kb/s upstream and 2Mb/s downstream on a broadband connection, but I
still get occasional breakups even when the ATA alone is engaged in a
call. If it was downstream of a router, it would not be able to give
priority to its own voip packets during a call. Oh, and I can just power
the modem and ATA to maintain voip with no other machines running for
environmental reasons when I don't need the rest of the network active.

As I have said before everything seems to work 95% of the time, but
requires this touching of the STUN setting in ekiga instances before
they can make calls. It is not a big deal, but it would be nice to
understand what is going on.

Maybe having the ATA up front is the unusual part?
