[Freeswitch-dev] bridging calls using mod_managed

Hi,

I did managed to get something to work. I placed complete code on pastebin:
http://pastebin.com/eCsYSdfk I don't know why exactly it works now, I think
it has something to do with a public decalration of my leg_a as managed
session and using that, now I pass the contect.Session every time and
create that as a local leg_a reference and that seems to work...

Still I have some problems with I need realy need somebody to help me
with...

1. immediately after the bridge (log says exact same timestamp) the HangUp
handler is invoked. (it seems as a separate part, as the rest of my code is
handled too) Why is the hangup handler called when the bridge is started
and how to avoid this?

2. After the bridge I need to get into a loop to continue my code while in
the bridge, and after the bridge, depending on who hung up. So after bridge
I go into while loop like:
     while(leg_a.bridged() && leg_b.bridged()) { }
But the both return false immediately. Al other functions (
contect.Session.Ready() ) return false too, though my code continues and
just continues my function. How can I make this work?

My (custom debug)log shows:
2012-01-09 10:29:42.111746 [INFO] sofia.c:819
