Callback issue

Hello,
Maybe this issue has been posted already, but i didn't find, so I'm sorry if it's a duplicate.
If you are calling a registerd personally callback by selecting the callback and clicking the "DIAL LEAD" Link the callback is dialed and if the called lead picks up the line the call is established and working fine.
But on the top the status message "STATUS: Calling: (xxx)xxx-xxxx UID: M0812130719000112627 Waiting for Ring... 45 seconds" is displayed any longer and counting the ringing seconds until 45 sec, and then you get a popup-message "Dial timed out..", but the call is active.
So it seems to be that the system is not recognizing, that the called lead has picked up the phone.
astguiclient version: 2.0.4.1RC3
I have replaced following files from the 2.0.4.1RC3 zip archive with the files from /svn/agc_2-X/branches/agc_2.0.4/www
vicidial.php, vdc_db_query.php, (at svn vicidial.php line 3218 is commented out).
Before replacing that files, the callback feature caused a firefox crash with popup flooding...
