Thanks for all the responds..
I have IPO essential license and Preferred VM pro license.I have tested in my laptop and two more another desktops with Windows 7 OS.I h stopped firewall,windows defender services. It was an upgrdade from 500 (version 5) to 500V2(8.1) and we replaced old license dongle after getting duplicate licenses for the new SD card.Everything on the license tab showing "valid" only.
VM pro server is not in domain and we don't have any domain infrastructure.
When i dialed *17 from an IP phone and did a trace on system status i can see the following things.There i noticed "Disconnect from Destination End "
Trace Output - All Buttons:
