Well, now I've disabled STUN again and I can still register to
ekiga.net.  So I think my siproxd server is making it work.  I tried no
STUN and no siproxd proxy, and registering to ekiga.net fails.

By the way, iptel.org claims that using their service, you should not
use STUN.  Their website states that they have a "server side NAT
traversal" solution in place.  I haven't fully tested it yet, but I plan
to.
