The UA in question is indeed a Grandstream phone and I

others showing this behaviour. On a quest for such agents you can
probably skip any agents without STUN support, I guess. Afaik, that does
not leave you with too many options. I personally only know about
Grandstream, X-ten and Snom. If you know others, I would be very
interesting to learn which ones.
iptel will have such soon, I will be happy to take any inquiries off-line.
On a side: A good start would also to avoid symmetric
NATs. I would love
to compile a list of routers which operate symmetric NATs to tell my
customers to avoid them. I tried a number of residential routers, but
all of them did some sort of coned NAT. Who could name symmetric NATs?
sipphone.com maintains a list of such NATs. for example, linux nats are
symmetric.
