asterisk users - May 2010 - Definie gtalk troubles over here

Hello everyone!
   So I tried to test gtalk with a friend. We could both see each other. He 
uses the gtalk application for Windows.
   So I tried to call him and he got a ringtone. But when he picked up, he got 
a missed.
   When he called me, he got a dial tone and then after one "ring" he
got a
woman saying: "Sorry, the person your are calling is not available. Please 
leave a message after the meep. Meep! :-)" But that certainly wasn't my
asterisk, at least not to my knowledge. I can't check in google itself, for 
it's graphical and I can't do that, for I'm blind.
   I have a full log here, if any one could help me work through it? I'm 
baffled and can't see real reasons for it. I rechecked, that my external IP 
was still correct and my JACK is running all the time. I don't know what to 
do.
   Warm regards
            Julien

Hi again!
   Just a short addition: I've looked a bit closer at the buddies list as
well
and I see, that I ahve no resources. Though my friend could see me and I tried 
sending a text message from freetalk (jabber-client) and it worked as well. I 
just thought, that might be of use.
   Can someone please help me?
   Kindest regards
            Julien
