Calls not passing through Agent

Hi Everyone,
Calls started not passing through to my agents after I upgraded my dialer from 2.0.4 to 2.0.5. There are calls waiting and in agent page I could see calls in queue but not passing dialer. I reverted back to 2.0.4 but I still have this issue. I restored all agi files of 2.0.4 but of no use.
Any help/guidance would be invaluable.
Thanks,
Prabhakar
