this seems quite interesting, but I still have a question: if this is
true how can [EMAIL PROTECTED] work?
With that service I can hear my voice back perfectly also without STUN:
maybe that client uses the address from which the IP packets are
originated instead of that supplied in the SIP protocol.

I'm sure it is. See this page about Fastweb IP mapping:
http://plany.fasthosting.it/natpool.html

Without STUN I can't get any audio from neither [EMAIL PROTECTED] nor
[EMAIL PROTECTED]; with STUN I can hear the recorded message from
[EMAIL PROTECTED] but I still get only silence from [EMAIL PROTECTED]

Anyway I think that this is probably not an Ekiga issue but just a
consequence of the different SIP implementations of the parties I'm
calling: am I right? Bad news for me in this case... Wengo's http
tunneling will be my last resort.

Thank you

Maurizio
