It is just a matter of setting a private address in the Contact header
of the SIP message, apparently.
Linphone seems to be the only one from the other phones you're refering
to do that.
But I think that's not correct to reject a REGISTER because of that. All
proxies (opensips, openser, kamailio) have support for NAT workarounds.
Furthermore in plenty of case (all people behind symmetric firewalls),
the phone's guessed external IP address port will be wrong. Indeed
you'll be lucky if the same external port of the firewall is used to
reach the proxy and the STUN server (the stun server is used to discover
the external IP and port).
For all theses reasons, proxies MUST be NAT aware.

As far as I know ekiga and linphone are very interoperable, which is
what everyone wants. Now the fact that a linphone client could use a
server hosted by ekiga.net is something different. The main purpose of
the ekiga server I guess is to let ekiga clients work with it. I would
understand perfectly that they don't care about linphone.
ekiga.net is not supposed to be a vendor independent service.

I recommend to use this one until sip.linphone.org becomes operationnal:
http://sip.antisip.com
As far as I know it interroperates with everyone.
Antisip is the company behind eXosip2 and also contributed to
mediastreamer2 development.
