The symptoms are caused by your "qualify=" lines. Every 60 seconds,
an "OPTIONS" request is sent from Asterisk to the destination. I
don't seem to see evidence that supports your statement that packets
to the 5060 port works and 5061 doesn't; it appears that both
requests are sending back the same 404 error.
This is a bug with the Sipura; actually, more like a missing feature.
I would say "Don't worry about it" since the added traffic keeps
your
NAT mappings in place. I'm sure Sipura will come up with a patch if
you and all your friends send in bugnotes to them.
