Ekiga should be automatically detecting things like STUN, etc. I
haven't used it in a few months, but it works very well. If it's not,
there's nothing anyone can really do.
Also, I really doubt you'll have consistent bandwidth at random hotel
wireless networks to really do video anyway. While I'm traveling, I
stick to voip only. Usually SIP (with STUN NAT traversal enabled). I
use project gizmo for most of that.
Note that STUN (NAT hole-punching anyway) is really a nasty hack anyway.
It's not guaranteed to work on all firewalls. Seems to work pretty
decently for me. Skype, ekiga, and project gizmo (a sip-only
soft-phone) all work with STUN quite nicely in my experience.
If ekiga is having a hard time building the STUN connection, all other
programs will have a hard time too.

No video support for any of those on linux.

OpenWengo doesn't do video anyway. But it is open source and there is a
linux download right on the page. That was the only reason I mentioned
it, in response to your complaint about being unable to buy or download
it for Linux.

No it's not enough. And it's likely not ekiga's fault either. Until
the world converts to IPv6, I have a sad feeling you're going to be
disappointed with all solutions on all platforms. STUN works very well
in a lot of cases. But it relies on what are essentially problems
(well, certain behaviors anyway) with the UDP implementation on the
router. That can never be guaranteed in any way.
