Titolo: VoIP via SIP e Fastweb

Hi!
I'm using VoIP here in Austria, and a friend of mine would like to use 
it to call his girlfriend in Rome. To bad, as it seems she uses Fastweb 
and her SIP-compatible, NAT friendly IP-Phone won't work (Grandstream 
ATA-286). Wow, Fastweb only assigns private IP adresses! I thought it 
was a joke when I first read that... However, the IP-Phone should work 
with NAT too, but it doesn't seem to work with the Fastweb NAT.
OK, so it seems that with "internet senza limiti" 20 hours of using a 
public IP are included. At least a little bit. She would have to 
activate public IP before placing a call or being called.
How does that work? I read, that you can activate the public IP on the 
Fastweb customer page. Can you assign this IP to one of the 3 devices 
connected, or does that allways apply to the device, from which you 
activate it. Because the ATA-286 VoIP adapter is of course connected to 
another port than her PC. So, can she activate the public IP from her PC 
for another connected device?
Does anybody know, if Fastweb might plan to offer free public IP 
adresses for everyone sometime?
And by the way, how can you find out the private IP adress of your 3 
devices connected to Fastweb-can you use it as a home LAN. The VoIP 
adapter won't show it's IP adress, but you have to know it to connect to 
the device in order to configure it.
Thank you for suggestions. Feel free to answer in Italian, it is just 
hard for me to write that in Italian, but I should understand. :)

Seems that you KNOW it. We will try.
Thanks!

 STUN server turned on.
I suppose You are using this typical configuration :
==

However, if You experience problems in making calls behind Dynamic NAT,
You can try without outbound proxy and/or STUN server as suggested in
the product FAQs.
According to receive phone calls from not-FastWeb customers, You can 
also activate the Public IP Address service of FastWeb from this page :

http://www.fastweb.it/ip_pubblico

once authenticated to the MyFastPage -> the IPPD service allows also to
have remote activation of devices/computers previously registered. You
may find all the instructions at the IPPD page. Since your friend has 
a contract with 20 hours monthly IPPD bundle, she may activate the
service in the "recurrent session" mode.

 service in the "recurrent session" mode.
What is "recurrent session" mode?

 What is "recurrent session" mode?
Recurrent sessions allow You to define hours/days in which have weekly
activations of the IPPD service. In this way You can have the same 
public IP address for all the duration of the recurrent session.

    NAT Traversal .: YES, STUN server is 
stun.sipgate.net:10000
 
Thanks, but it didn't help.
Next week we'll check if it works with a public IP.
