One more clarification then: your bandwidth consumption is in no way affected by Jingle Nodes. Use of JN only has an impact on the bandwidth consumption of your service provider ... but that's for them to consider.
It is exactly your bandwidth I do consider especially for a free service. I mean, I have all this unused bandwidth that I'm paying my ISP for and than someone on the net has to duplicate it because my router sucks? That sucks! I just try to enforce endpoint-to-endpoint here... Even though with little luck. :-\ (And of course this router is lent to me by that same ISP who just happens to sell SIP services as well...)
I must have missed your report on that one. My jit.si account has contacts on gmail, jabber.org and other servers and we haven't really noticed any interop problems. Whic networks have you seen problems with?
I have not reported it yet, because I thought that you will probably change your configuration quite often in the near future anyway. Well so here is the report: When I add peers from a different server to my jit.si account (In my case the would be users of jabber.org and jabber.ccc.de, but also firstname.lastname@example.org did not do the trick.), the authorization request never seems to hit them. Therefore I suspected, that you just have not enabled federation yet which obviously by now is not the case. (The problem is probably reproduced by at least of my friends, but I have to check on that before confirming anything...)
as it always checks for ADDR:PORT combinations?)
Didn't get this part.
Ok, sorry, confused that one: I thought that because STUN will discover the outside address and port, my peer will know about the unique outside port even it is endpoint dependent. But of course, he will know the unique port for the STUN server which is not very helpful at all... (There is no way to get around this without relays or static forwarding, is there? Well, this sucks as well...)
Care to attach the logs of such a session?
Guess I have some log creation to do... But this will probably take to the middle of the coming week as I have to recruit the corresponding "endpoints" again.
P.S.: Sorry for the derailings of my language. I hope nobody minds.
